HTTP4

The http4 package provides enhanced HTTP request functionality in Flutter by leveraging the http package and http_interceptor for customizable HTTP requests with additional features and a new call-to-action style.

Features

• HTTP Methods: Simplified HTTP methods (GET, POST, PUT, PATCH, DELETE, MULTIPART) with customizable headers, parameters, and retry policies.
• HTTP Interceptors: Ability to use interceptors for modifying request headers, logging, and retrying failed requests.
• Configurable Base URL: Configure a base URL for all HTTP requests within the package.
• Debug Mode: Enable debug mode to print detailed information about HTTP requests and exceptions.

Installation

Add lazylist to your pubspec.yaml file:

dependencies:
    http4: ^1.0.0

Usage

1st way

import 'package:http4/http4.dart';

void fetchData() async {
  final http4 = Http4();

  final response = await http4.get(
    '/api/data',
    headers: {'Authorization': 'Bearer <token>'},
    params: {'page': 1},
    retryPolicy: RetryOptions(maxAttempts: 3),
  );

  if (response.isSuccessed && response.isOkey) {
    // Handle successful response
    print('Response: ${response.decodedBody}');
  } else {
    // Handle failed response
    print('Request failed');
  }
}

2nd way (inherit from Http4)

import 'package:http4/http4.dart' as http4;

class ExampleService extends http4.Http4 {
  Future<List<Map<String,dynamic>>> fetchData() async {
    final response = await get(
      '/posts?_page=1&_per_page=10',
      interceptors: [AuthInterceptor()],
    );

    return response.decodedBody;
  }
}

How to use interceptor

import 'package:http4/http4.dart' as http4;

class ExampleService extends http4.Http4 {
  Future<List<Map<String,dynamic>>> fetchData() async {
    final response = await get(
      '/posts?_page=1&_per_page=10',
      interceptors: [
        AuthInterceptor(token: 'Your-Token-Here'),
      ],
    );

    return response.decodedBody;
  }
}

class AuthInterceptor extends http4.InterceptorContract {
  late String token;

  AuthInterceptor({
    required this.token,
  });

  @override
  Future<http4.BaseRequest> interceptRequest(
      {required http4.BaseRequest request}) {
    request.headers.addAll({'Authorization': 'Bearer $token'});

    // Before sending the request, Authorization will add to the headers
    return Future.value(request);
  }

  @override
  Future<http4.BaseResponse> interceptResponse(
      {required http4.BaseResponse response}) {
    if (response.statusCode == 401) {
      print('Unauthorized request');
      // After calling the request, it will be redirected to the login page
    }

    return Future.value(response);
  }
}

Configuration

To configure the base URL and debug mode, use Http4Config:

final config = Http4Config();
  config.baseUrl = 'https://api.example.com';
  config.debugMode = true;
