Alice

Alice is an HTTP Inspector tool for Flutter which helps debugging http requests. It catches and stores http requests and responses, which can be viewed via simple UI. It is inspired from Chuck (https://github.com/jgilfelt/chuck) and Chucker (https://github.com/ChuckerTeam/chucker).

Overlay bubble version of Alice: https://github.com/jhomlala/alice

Supported Dart http client plugins:

Dio
HttpClient from dart:io package
Http from http/http package

Generic HTTP client

Features:
✔️ Detailed logs for each HTTP calls (HTTP Request, HTTP Response)
✔️ Inspector UI for viewing HTTP calls
✔️ Statistics
✔️ Support for top used HTTP clients in Dart
✔️ Error handling
✔️ HTTP calls search ✔️ Bubble overlay entry

Install

Add this to your pubspec.yaml file:

dependencies:
  flutter_alice: ^1.0.1

Install it

$ flutter pub get

Import it

import 'package:flutter_alice/alice.dart';

Usage

Alice configuration

Create Alice instance:

// Define a navigator key
final navigatorKey = GlobalKey<NavigatorState>();

// Create Alice with the navigator key
final alice = Alice(navigatorKey: navigatorKey);

Add navigator key to your application:

MaterialApp(
  navigatorKey: navigatorKey,
  home: YourHomeWidget(),
)

You need to add this navigator key in order to show inspector UI.

Optional: To use bubble overlay, wrap your app with OverlaySupport:

// Don't forget to import overlay_support package
import 'package:overlay_support/overlay_support.dart';

OverlaySupport(
  child: MaterialApp(
    navigatorKey: navigatorKey,
    home: YourHomeWidget(),
  ),
)

HTTP Client configuration

For Dio

Add interceptor to your Dio instance:

final dio = Dio();
dio.interceptors.add(alice.getDioInterceptor());

For HTTP package

You can use extension methods for cleaner code:

// Import extensions
import 'package:flutter_alice/core/alice_http_extensions.dart';

// Use extension methods
http
  .get(Uri.parse('https://jsonplaceholder.typicode.com/posts'))
  .interceptWithAlice(alice);

// For POST requests with body
http
  .post(Uri.parse('https://jsonplaceholder.typicode.com/posts'), body: body)
  .interceptWithAlice(alice, body: body);

Or use the standard approach:

http.get(Uri.parse('https://jsonplaceholder.typicode.com/posts')).then((response) {
  alice.onHttpResponse(response);
});

// For POST requests with body
http.post(Uri.parse('https://jsonplaceholder.typicode.com/posts'), body: body).then((response) {
  alice.onHttpResponse(response, body: body);
});

For HttpClient from dart:io

You can use extension methods:

// Import extensions
import 'package:flutter_alice/core/alice_http_client_extensions.dart';

// Use extension methods
httpClient
  .getUrl(Uri.parse("https://jsonplaceholder.typicode.com/posts"))
  .interceptWithAlice(alice);

// For POST requests with body
httpClient
  .postUrl(Uri.parse("https://jsonplaceholder.typicode.com/posts"))
  .interceptWithAlice(alice, body: body, headers: Map());
