Double cursor using iOS floating cursor (keyboard cursor move with spacebar) #89228
Description
I created this Issue for the last bug described in #17030, which we also just encountered, because the #17030 got closed.
Steps to Reproduce
OS: iOs and iPadOS
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Center(
child: TextField(),
),
),
);
}
}
Enter so much text into the TextField, that the TextField starts scrolling. Then try to scroll with two fingers, on the spacebar, horizontally through the text.
Expected results: The curser moves with the fingers and scrolls horizontal through the TextField.
Actual results: A second curser appears, which moves separately to the original curser, and the TextField doesn't scroll horizontally.
