Steps to reproduce

  1. Run this code sample on iOS.
  2. Long press on selectable text.

I've verified on Android, MacOS & Web, it is working fine. Faced this issue while triaging #91524.

Please check #91524 (comment).

I reproduced the problem without using flutter_markdown.

Expected results

The iOS context menu (copy/select) should appear without throwing errors.

Actual results

The context menu appears, and the system logs an error about an inactive text input connection.

Code sample

Run this code sample 
import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: const Text('Selection Error')),
        body: const Padding(
          padding: EdgeInsets.all(16),
          child: Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: [
              SelectableText(
                'This is a selectable paragraph.\nLong press me on iOS.',
              ),
            ],
          ),
        ),
      ),
    );
  }
}
