Text field loses focus when changing Gboard language on Android

Mr-Pepe commented 3 weeks ago

Steps to reproduce

On a Pixel 8 with Gboard:

Run the app with the provided sample code
Change the keyboard input language

Expected results

The text field stays focused and the keyboard stays visible, so I can keep typing.

This is the behavior of all other apps on my phone.

Actual results

The text field loses focus and the keyboard disappears.

Code sample

```dart import 'package:flutter/material.dart'; void main() { runApp(const MyApp()); } class MyApp extends StatelessWidget { const MyApp({super.key}); @override Widget build(BuildContext context) { return const MaterialApp( home: MyHomePage(), ); } } class MyHomePage extends StatefulWidget { const MyHomePage({super.key}); @override State createState() => _MyHomePageState(); } class _MyHomePageState extends State { @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: const Text("Keyboard focus"), ), body: const Center( child: TextField( autofocus: true, ), ), ); } } ```

Thanks for the report @Mr-Pepe

Although I don't have Pixel device, but I tried on Pixel emulator with which I didn't observe the reported behavior. I also tried on Samsung S10 with same result. Can you provide a short video of the behavior ?

@darshankawar Here you go :)

Thanks for the video. Can you provide Gboard details if possible and just to make sure, this doesn't occur with default virtual keyboard correct ?

Mr-Pepe commented 3 weeks ago

I just tried with Microsoft SwiftKey and that doesn't have the issue.

The Gboard version is 14.1.04.621126403. Let me know if there is more that I can do.

Anderillo commented 3 weeks ago

I've also been experiencing this exact same issue, and would love a fix whenever possible.

danagbemava-nc commented 2 weeks ago

Reproducible using the code sample and steps outlined above.

Tested on my Pixel 7.

I can reproduce this on my physical Pixel 6, though only when I cause the "Change keyboard" dialog to appear and make a selection, not when I just tap the globe 🌐 key to immediately switch languages.

I've confirmed that this is not coming from the framework. The framework does not send TextInput.hide when I reproduce the bug.

I see the engine calls hideSoftInputFromWindow in two places, maybe one of those are causing it to close: https://github.com/flutter/engine/blob/8eba63f29b8b26931496807cb4fc2fed8e4e3258/shell/platform/android/io/flutter/plugin/editing/TextInputPlugin.java#L371, https://github.com/flutter/engine/blob/8eba63f29b8b26931496807cb4fc2fed8e4e3258/shell/platform/android/io/flutter/plugin/editing/TextInputPlugin.java#L401.

And here's an old issue that sounds vaguely similar: https://github.com/flutter/flutter/issues/34169.

Maybe someone with more Android expertise would have a hunch @reidbaker ?

Edit: Oh and I see this in my console when I reproduce it:

I/ImeTracker(15092): com.example.sandbox:eb0c645b: onRequestHide at ORIGIN_CLIENT_HIDE_SOFT_INPUT reason HIDE_SOFT_INPUT_BY_INSETS_API

This does not happen if the app is run as a web app. No idea if that's relevant.
