Color of Japanese text conversion box is invisible

[junka-0]

Steps to reproduce

1. Prepare a flutter project (flutter version 3.7.7)
2. Run iPad simulator (iOS 17.2)
3. Enable I/O > Keyboard > Connect Hardware Keyboard
4. Type some Japanese-kana text and try to convert it to Kanji

Expected results

I would like to know how to customize the text color and background color of the suggestion box.

Actual results

It is hard for users to see which suggestion is selected because the text color and background color of suggestion box are almost the same.

Code sample

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( title: 'Flutter Demo', home: MyHomePage(title: 'Demo Page'), ); } } class MyHomePage extends StatefulWidget { const MyHomePage({super.key, required this.title}); final String title; @override State createState() => _MyHomePageState(); } class _MyHomePageState extends State { @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text(widget.title), ), body: Center( child: Column( mainAxisAlignment: MainAxisAlignment.center, children: [ TextFormField(), ], ), ), ); } } ```

I believe this is fixed in a newer version of Flutter. Could you check if this works on the latest stable?

I would like to know how to customize the text color and background color of the suggestion box.

Is this a feature request, or you would like to use the default text color (instead of the white color that made the candidate text invisible) for the currently selected IME candidate?

I confirmed that it works fine on new version of flutter. Thank you 🙇

It is not a request. But if there is a way other than upgrading Flutter version, I would like to know it.

Ah I thought you wanted to change the candidate text to use a custom color. Closing as a duplicate of https://github.com/flutter/flutter/issues/132548
