Description

opened on Jan 28, 2026

Steps to reproduce

  1. Register the app to handle geo: URIs in Android
  2. Open a geo link, such as geo:51.5,0.0

Expected results

The app successfully process the link and handle it.

Actual results

The app throws an exception.

Specifying onEnter to pre-handle geo: links and block navigation doesn't solve the issue.

Code sample

Code sample 
import 'package:flutter/material.dart';
import 'package:go_router/go_router.dart';

final _router = GoRouter(
  routes: [
    GoRoute(
      path: '/',
      builder: (context, state) =>
          MyHomePage(title: 'Flutter Demo Home Page', uri: state.uri),
    ),
  ],
);

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp.router(routerConfig: _router);
  }
}

class MyHomePage extends StatelessWidget {
  const MyHomePage({super.key, required this.title, required this.uri});

  final String title;
  final Uri uri;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(title),
      ),
      body: Center(
        child: Text(
          uri.toString(),
          style: Theme.of(context).textTheme.headlineMedium,
        ),
      ),
    );
  }
}
