In this Tutorials, We are going to learn how to embed PowerBI Reports on Jupyter Notebook. So first of all we will start with Basic requirement for this Task.
Jupyter Notebook is a web based Computing platform. It is also web applications for creating computational documentations
Installation of power BI client:-
pip install powerbiclient
run the above installation cmd in your command prompt or Notebook to install power bi.
Authenticate to Power BI and acquire an access token
Acquire a token using Device Code flow
To authenticate users on devices or operating systems that don’t provide a web browser, device code flow let’s the user use another device such as a computer to sign in interactively.
By using the device code flow, The application follow two-step process that for OS and designs
get_access_token() :- Get access token for OAuth2 access to MS PowerBI Shell
from powerbiclient.authentication import DeviceCodeLoginAuthentication
device_auth = DeviceCodeLoginAuthentication()
token_with_device_code = device_auth.get_access_token()
After Running Bunch of Code, we will get message to Sign in for Device Login
After Clicking on Next Button it will ask to select Microsoft Account and Click On Continue
After Signed in Microsoft Account It will display below message that means we have successfully access Power BI Shell. & make sure you don’t close the Window.
After getting the access from Microsoft We will get Device Authentication message.
After this we are ready embed Power BI Report.
Power BI report embedding widget
Arguments:
group_id string – Required. Id of Power BI Workspace
report_id string – Optional. Id of Power BI report. auth object – Optional. We have 3 authentication options to embed a Power BI report:
Access token (string)
Authentication object (object) – instance of Authentication Result (DeviceCodeLoginAuthentication)
If not provided, Power BI user will be authenticated using Device Flow authentication
Returns:
object – Report object
Steps:-
After Completing Authentication
Go To Power BI Workspace
Click on Report that you want to Share
Copy the Report and Group from the file URL and paste into Respective Values.
JWT Stands for (JSON Web Token) it a popular mechanism by which we can implementing authentication and authorization of a users in web applications, so basically in JWT token we store user data and the token expire time which will be in encrypted, It can be used in any application to authenticate users. Here’s how we can use JWT Web tokens in ReactJS application:
How Frontend and backend works with JWT Token
From Frontend Application we send the login credentials using login form to the backend API server.
Then backend API will verify the credentials passed by users exist of database, if exist then backend will generate a JWT token by storing all the user data into the token.
Then backend API respond the JWT token back to the frontend.
Now to keep user logged into the web application, we need to store the JWT token in browser local storage or as a cookie.
Now whenever frontend wants some data from backend, it sends JWT token with request parameter to the backend.
The backend verifies if the JWT token passed is valid or no, if JWT token is not expired and is valid then backend will pass the requested data back to the frontend.
Hi Guy’s Welcome to Proto Coders Point. In this Flutter dart article let’s checkout How to calculate sum of array list, Find the smallest & largest number in a given list by using list fold method.
Dart fold Syntax
Future<S> fold<S>(initialValue,<function>( S previous, T element ){
// your operation here
})
In Flutter dart fold method, accept 2 parameters i.e. first-> initialValue & second -> a function that content 2 parameter (Previous & a element from the list). Here the previous value will be initialValue & will only change when programmer wants to & element will item from a list basically it keep changing in a loop.
Let’s Understand the Fold Method using below Examples
1. Calculate the Sum of List Element
In below code, The initial value will be first item from the list i.e. 3, Now in first loop value of sums = 3 and ele = 3 so 3+3=6, then in next iteration sums = 6 and ele = second item from the list i.e. 4, so 6 + 4 = 10, and then in third iteration value of sums get updated to sums = 10 and ele = next item i.e. ele = 5, so 10 + 5 = 15. like this the loop gets iterating until the end of the list item and we get addition of list as 18.
void main(){
final numbers = [3,4,5,1,2];
final sum = numbers.fold(numbers.first,(sums,ele){
return sums + ele;
});
print(sum); // 36
}
2. Find the largest number in list using fold method
In below code, To find the greatest number from a given list. Here initialValue is the first item from the list and it automatically assumed a max i.e. the largest element, and ele = 3 that keep are changing on each iteration, In the loop we check if the max < ele, if true then max is set to ele and thus we get the largest number from the given list.
void main(){
final numbers = [3,4,5,1,2,4,2,1,4,7,0];
final largest = numbers.fold(numbers.first,(max,ele){
if (max < ele){
max = ele;
}
return max;
});
print(largest); // 7
}
3. Find the smallest number in list using fold method
In below code, To find the lowest number from a given list. Here initialValue is the first item from the list and it automatically assumed a min i.e. the smallest element, and ele = 3 that keep are changing on each iteration, In the loop we check if the min > ele, if true then min is set to ele and thus we get the smallest number from the given list.
void main(){
final numbers = [3,4,5,1,2,4,2,1,4,7,-1];
final smallest = numbers.fold(numbers.first,(min,ele){
if (min > ele){
min= ele;
}
return min;
});
print(smallest); // -1
}
Now build a complete flutter using online flutter flow
You’re probably already familiar with Flutter, Google’s incredibly useful UI toolkit that has simplified the process of creating apps. FlutterFlow, a drag-and-drop interface created by two former Google engineers that makes the creation of mobile apps for both iOS and Android, was released in May 2021, making things even simpler.
Everything you need to know about Flutter Flow, including its definition, features, advantages, and cost, will be covered in this article. But first, let’s take a quick look at our favorite Flutter to provide you with some context.
Flutter Flow is a visual development platform that allows developers and designers to build mobile and web applications without having to write code manually. It utilizes a drag-and-drop interface, allowing users to create UI elements and connect them together with data sources and events. The platform generates the Flutter code in the background, which can be exported and further customized if needed. Flutter Flow also supports collaboration, version control, and integration with other development tools.
Two former Google engineers founded Flutter Flow to serve as a third-party visual app builder for the Flutter framework. It was showcased at Google I/O and is supported by Y Combinator.
flutterflow.io
As we’ve already mentioned, FlutterFlow is a drag-and-drop mobile app development tool that runs in the browser. This implies that you don’t need to write any code in order to create amazing custom apps in less than an hour. Consider it the Wix or GoDaddy of mobile applications.
The 2.0 version of the interface, which was released at the start of October, is already available. Without giving away its features, there isn’t much more we can say, so let’s get started!
Features:
UI elements and templates – You can choose from over 50 screen templates, over 40 pre-built widgets, and numerous third-party connectors (like Braintree and Google AdMob) to save time.
User authentication – Integrating Firebase, Google, and Facebook logins only requires dragging a button.
Development for both iOS and Android – You can simultaneously create apps for iOS and Android without writing any code.
The ability to create apps without writing any code may seem obvious, but it is by far FlutterFlow’s most alluring feature.
Guided troubleshooting – You can easily avoid and fix potential issues with real-time feedback and error correction.
Guided troubleshooting – You can easily avoid and fix potential issues with real-time feedback and error correction.
Obtain the source code You are in charge of your own work, and it’s simple to download the clear, understandable source code for your mobile application.
Firebase makes it simple for you to set up data infrastructure and connect to live data, allowing you to build up and add live data to your app.
Yes, you can follow these steps to create your first app in FlutterFlow:
1): Create a new project after creating an account on the FlutterFlow website (https://flutterflow.io).
2): When you are in the project, a canvas will appear on the right side of the screen, where you can drag and drop different widgets to build the user interface (UI) of your app. Pick a widget from the left-side panel and drag it onto the canvas to get started.
3): Once you’ve added a few widgets, you can customize them by selecting them and using the options in the Properties panel on the right side of the screen. You can also add new pages to your app by clicking the “Add Page” button in the top-left corner of the screen.
4): Use the Actions panel on the left side of the screen to add functionality to your app. You can include actions like going to a different page, submitting a form, or calling an API here.
5): By selecting the “Preview” button in the top-right corner of the screen, you can view a preview of your app at any time. By doing so, a new tab will open up where you can view how your app functions and appears.
6): When you’re satisfied with your app, click the “Publish” button in the top-right corner of the screen to make it public. Your app’s code will then b
e generated, which you can download or upload right away to a hosting platform.
7): Congratulations on creating your first FlutterFlow app!

In this Flutter dart article, Let’s go through different way through which we can calculate sum of array element. In dart array are called as list, let’s checkout how to perform addition of all the elements in a given dart list.
There are many ways by which we can get sum of array element in dart i.e by using normal loop like for loop or by using dart inbuild functions.
Sum of list using dart for loop
void main(){
final numbers = [1,4,2,3,6,4,2,1,4,5,0];
var sum = 0;
for(var i=0;i<numbers.length;i++){
sum += numbers[i];
}
print(sum);
}
Sum addition of array element using dart forEach loop
void main(){
final numbers = [3,4,5,1,2,4,2,1,4,7,0];
var sum = 0;
numbers.forEach((val){
sum += val;
});
print(sum);
}
Sum of array list using reduce function
void main(){
final numbers = [3,4,5,1,2,4,2,1,4,7,0];
var sum = numbers.reduce((a,b)=>a+b);
print(sum);
}
Addition of all element in dart list using collection package sum function
import 'package:collection/collection.dart';
void main() {
final numbers = [1, 150, 10, 134, 5, 8];
var sum = numbers.sum;
print(sum);
}
Hi Guy’s, Welcome to Proto Coders Point. In this Flutter Article let’s learn how to apply typewritter typing animation effect to flutter text widget.
The Typewriter text effect is an animation where a text is been typed automatically letter by letter, and it feels like the text is been typed one by one.
This kind of animation effect on text is used when you want to grab attention on your app user and make them focus on the Text that is appearing on the screen.
The logic to make text to be typed letter by letter on the screen is by using substring() method.
Here we have a function _typeWrittingAnimation, that keeps on calling itself after every milliseconds say 100 milliseconds, We have 2 integer variable _currentIndex & _currentCharIndex. The _currentCharIndex gets incremented by 1 until it is not end of the string, once the currentCharIndex reaches the end of the string,The _currentIndex is set to next List Item String in the given list.
