Flutter GoRouter Extension #

A Flutter package that extends go_router with Android-style navigation behaviors.

Features #

• pushWithSetNewRoutePath: Simulates Android's FLAG_ACTIVITY_CLEAR_TOP | FLAG_ACTIVITY_NEW_TASK behavior
• Supports dynamic route parameters (e.g., /user/:id)
• Supports wildcard routes (e.g., /files/*)

Installation #

Add this to your pubspec.yaml:

dependencies:
  flutter_go_router_extension: ^1.0.2

Usage #

pushWithSetNewRoutePath #

When navigating to a page that already exists in the stack, it clears all pages above and including that page, then pushes a new instance of the target page.

import 'package:flutter_go_router_extension/flutter_go_router_extension.dart';

// In your widget
ElevatedButton(
  onPressed: () {
    context.pushWithSetNewRoutePath('/user/123');
  },
  child: Text('Go to User'),
)

Example #

If the original stack is:

/home -> /user/123 -> /user/123/posts -> /comments

And you call:

context.pushWithSetNewRoutePath('/user/123');

Processing steps:

1. Route /user/:id converts to RegExp: ^/user/[^/]+$
2. Check /comments - No match, remove
3. Check /user/123/posts - No match, remove
4. Check /user/123 - Match found

Resulting stack:

/home -> /user/123 (new instance)

How It Works #

1. Path to Regex Conversion: Dynamic parameters (:param) are converted to [^/]+, wildcards (*) to .*
2. Stack Traversal: Iterates from the top of the navigation stack
3. Match & Clear: When a matching route is found, all routes above it (including itself) are removed
4. Push New Instance: A fresh instance of the target page is pushed onto the stack
