[ykyouhei]

Platform

iOS26

Plugin

share_plus

Version

11.0.0

Flutter SDK

3.32.4

Steps to reproduce

1. Call the SharePlus.instance.share method with the await keyword.
2. On iOS 26 devices only, the share method does not return a value or throw an exception.

Code Sample

import 'package:flutter/material.dart';
import 'package:share_plus/share_plus.dart';

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

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

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  bool _isSharing = false;

  Future<void> _share() async {
    if (_isSharing) return;

    setState(() => _isSharing = true);

    try {
      // ! On iOS 26, the share method doesn't return a result or throw exceptions
      final result = await SharePlus.instance.share(
        ShareParams(text: 'dummy share text'),
      );
      print('Share result: $result');
    } catch (e) {
      print('Error sharing file: $e');
    } finally {
      setState(() => _isSharing = false);
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text('share_plus bug report.'),
            _isSharing
                ? const CircularProgressIndicator()
                : const Text('Press the button to share.'),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _share,
        tooltip: 'Share',
        child: const Icon(Icons.share_outlined),
      ),
    );
  }
}

Any update?

// We use dealloc as the share-sheet might disappear (e.g. iCloud photo album
// creation) and could then reappear if the user cancels
- (void)dealloc {
  if (self.completed) {
    self.result(self.activityType);
  } else {
    self.result(@"");
  }
}

I don’t think dealloc should be used as the standard for the end callback. I believe the result should be returned inside activityViewController.completionWithItemsHandler.

@miquelbeltran
What do you think? I’ll create a request to fix this issue.

Yes, submit a PR please.

I don't have equipment to develop a solution or to test iOS 26 beta, so someone else will have to chip in.

Everyone else, please stop asking for updates. If you want to help, submit a fix or help debug a solution.

Hi,
I was wondering if this issue could be related to #3645
In our case, the behavior only happened when the app was built with Xcode 26.
