Description:

flutter feature network

Overview #
flutter_feature_network is a library designed to simplify and enhance network operations in
Flutter applications.
This library provides a suite of tools and methods to manage network requests efficiently, including
Dio client setup, logging, request identification, and SSL security.
Methods #
Get Dio Client
Generate Dio Client For HTTP Transaction.
final dioClient = FeatureNetworkRepositoryImpl().getDioClient();
// or
final dioClient = FlutterFeatureNetwork.getDioClient();

Parameter Name
Type
Required
Description




receiveTimeout
Duration
no
The maximum amount of time the client will wait to receive data from the server.


connectTimeout
Duration
no
The maximum amount of time allowed for the client to establish a connection to the server.


sendTimeout
Duration
no
The maximum amount of time allowed for the client to send the request data to the server.


baseUrl
String
no
The base URL for all requests made by this client.


headers
String
no
The default headers to be included in every request.


interceptors
List
no
A list of interceptors that will be added to the Dio client for request/response modifications.


trustedCertificateBytes
List
no
A list of bytes representing trusted certificates for SSL pinning. Only one of trustedCertificateBytes or allowedFingerprints allowed.


allowedFingerprints
List
no
A list of allowed SSL certificate SHA fingerprints for secure connections. Only one of trustedCertificateBytes or allowedFingerprints allowed.



Is Connection Secure
This is will checked if the connection using certificate is secure.
if connection is secure, it will return true, otherwise it will return false.
final isSecure = FeatureNetworkRepositoryImpl().isConnectionSecure(
serverUrl: 'https://jsonplaceholder.typicode.com/',
sha: SHA.SHA_256,
allowedSHAFingerprints: [
'14f9996f9481eac7f9c005f6954c2f032d8e9cb13d4440ebed35f14bed22c43f',
],
);
// or
final isSecure = FlutterFeatureNetwork.isConnectionSecure(
serverUrl: 'https://jsonplaceholder.typicode.com/',
sha: SHA.SHA_256,
allowedSHAFingerprints: [

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's forked from: https://pub.dev/packages/alice










// Setup Alice
final alice = Alice(showNotification: true, showInspectorOnShake: true);
// Put in Material App
@override
Widget build(BuildContext context) {
return MaterialApp(
navigatorKey: alice.getNavigatorKey(),
title: 'Flutter Feature Network',
theme: ThemeData(
colorScheme: ColorScheme.fromSeed(seedColor: Colors.blueAccent),
useMaterial3: true,
),
home: const MainPage(),
);

// ...
interceptors: [
LoggerInterceptor(),
],
// ...
);
// or
final dio = FlutterFeatureNetwork.getDioClient(
// ...
interceptors: [
LoggerInterceptor(),
