FlutterFlow and Khan Academy API integration: Step-by-Step Guide 2024

Discover a step-by-step guide to seamlessly integrate FlutterFlow with the Khan Academy API. Enhance your app's functionality with educational content in just a few simple steps.

What is Khan Academy API?

The Khan Academy API is a program interface developed by Khan Academy, a non-profit educational organization. This API provides developers access to a variety of data from the Khan Academy website, allowing them to create apps and services that interact with Khan Academy's resources. This can include user profiles, badges, videos, exercises and more. The intent is to encourage the development of educational tools that use and enhance Khan Academy's extensive collection of learning materials.

How to integrate FlutterFlow with Khan Academy API?

 

Step 1: Create a Khan Academy API Key

  • Visit the Khan Academy developer portal:
    • Navigate to the Khan Academy API page.
    • If you don’t already have an account, you’ll need to sign up.
  • Create an Application:
    • After logging in, navigate to the 'My Applications' section.
    • Click on 'Create a New Application' or a similar option.
    • Fill in the necessary details such as the name and description of your application.
    • You’ll receive an API Key and sometimes a Client Secret. Store these securely as you'll need them for authentication later.
 

Step 2: Set Up Your FlutterFlow Project

  • Log into FlutterFlow:
  • Create a New Project:
    • Once logged in, click on 'Create New Project'.
    • Follow the prompts to set up a new project, naming it appropriately.
  • Add Dependencies:
    • Navigate to the 'Pubspec.yaml' file in your FlutterFlow project.
    • Add the following dependencies for HTTP requests and JSON parsing:
    •         
          dependencies:
            http: ^0.13.3
            json\_annotation: ^4.4.0
          dev\_dependencies:
            build\_runner: ^2.1.4
            json\_serializable: ^4.1.3
          
          
 

Step 3: Configure Authentication

  • Set Up HTTP Client:
    • Open the Dart file where you intend to make the API requests.
    • Import the required packages:
    •         
          import 'package:http/http.dart' as http;
          import 'dart:convert';
          
          
  • Store Your API Key:
    • You can store your API key in a separate Dart file for better security:
    •         
          const String KHAN_API_KEY = "your_khan_academy_api_key";
          
          
 

Step 4: Make API Requests

  • Create a Function for Fetching Data:
    • Define a function to make GET requests to the Khan Academy API:
    •         
          Future fetchKhanAcademyData() async {
            final response = await http.get(
              Uri.parse('https://www.khanacademy.org/api/v1/exercises'),
              headers: {
                'Authorization': 'Bearer $KHAN_API_KEY',
              },
            );
      
            if (response.statusCode == 200) {
              var data = jsonDecode(response.body);
              print(data);
            } else {
              throw Exception('Failed to load data');
            }
          }
          
          
  • Call the Function:
    • Within your application’s main logic or within a specific widget, call the function:
    •         
          @override
          void initState() {
            super.initState();
            fetchKhanAcademyData();
          }
          
          
 

Step 5: Display the Data in FlutterFlow

  • Create a Data Model:
    • Define a Dart class to map the JSON data:
    •         
          class Exercise {
            final String title;
            final String url;
      
            Exercise({required this.title, required this.url});
      
            factory Exercise.fromJson(Map json) {
              return Exercise(
                title: json['title'],
                url: json['url'],
              );
            }
          }
          
          
  • Parse the JSON Data:
    • Modify the fetchKhanAcademyData function to parse the JSON data into Dart objects:
    •         
          List exercises = [];
      
          Future fetchKhanAcademyData() async {
            final response = await http.get(
              Uri.parse('https://www.khanacademy.org/api/v1/exercises'),
              headers: {
                'Authorization': 'Bearer $KHAN_API_KEY',
              },
            );
      
            if (response.statusCode == 200) {
              var data = jsonDecode(response.body) as List;
              exercises = data.map((json) => Exercise.fromJson(json)).toList();
              setState(() {});
            } else {
              throw Exception('Failed to load data');
            }
          }
          
          
  • Display Data Using Widgets:
    • Use Flutter widgets to display the fetched data. For instance:
    •         
          @override
          Widget build(BuildContext context) {
            return Scaffold(
              appBar: AppBar(
                title: Text('Khan Academy Exercises'),
              ),
              body: ListView.builder(
                itemCount: exercises.length,
                itemBuilder: (context, index) {
                  return ListTile(
                    title: Text(exercises[index].title),
                    onTap: () {
                      // Handle tap events, maybe open a URL
                    },
                  );
                },
              ),
            );
          }
