Steps to Reproduce

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: TextField(
          autofocus: true
        ),
      )
    );
  }
}
  1. run above sample in iOS
  2. change keyboard input language to Spanish (Spain)
  3. type [
  4. type a

Expected results: à

Actual results: `à

we tested it on iOS/Android with external keyboard. both native behaviors showing the accented a without additional prefix `. in Flutter, it shows two words ` and à.

    It seems that we also have the same issue with the Physical keyboard having an input language as Portuguese (Brazil).

    1. type ˜
    2. type a
    3. It should become ã but it is not.

    Any updates on this problem? I'm not be able to use accents when I connect an external keyboard to my device. So for example, when try to achieve a work like camión I get cami´on.

    I have the same problem with Flutter (Channel stable, 3.7.6, on Microsoft Windows [version 10.0.19044.2604], locale pt-BR).
    I develop on Windows, but I compile for IOS and test on an IOS with an external keyboard.

    This issue is reproducible on the latest stable and master channels.

    Verified with Vietnamese by two methods:

    Using scrcpy

    • Input: a + s
    • Expected result: á
    • Actual result: a´a

    Connect with physical keyboard via Bluetooth (switching to Vietnamese language)

    • Input: a + s
    • Expected result: á
    • Actual result: as

    Just so it's not lost, here were my notes on the iOS issue that was deduplicated to this one: #146486 (comment)

    On iOS, pressing ALT-u + u on an external keyboard should produce ü. However, it produces ¨ü:

    1. I press ALT-u
    2. This calls [FlutterTextInputView setMarkedText:selectedRange:]
    3. The framework receives a TextInputClient.updateEditingState message with value ¨
    4. I press u
    5. This calls [FlutterTextInputView insertText:]
    6. The framework receives a TextInputClient.updateEditingState message with value ¨ü

    Apple's Handling text interactions in custom keyboards docs state:

    Calling setMarkedText selects the text specified by range. Subsequent insertions replace the characters selected in the range. In the example above, a space with a combining acute accent is shown. If the next character input by the user is an a, you could then insert a combined á.

    This indicates that [FlutterTextInputView insertText:] needs to be updated to replace the characters that were selected by [FlutterTextInputView setMarkedText:selectedRange:]'s range.
