how to remove text field cursor bubble in flutter

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(
        textSelectionTheme: TextSelectionThemeData(
          selectionHandleColor: Colors.transparent,
        ),
      ),
      home: Scaffold(body: Center(child: TextField())),
    );
  }
}

TextField set enableInteractiveSelection property to false can resolve this issue.

 enableInteractiveSelection: true,

You will have to change the theme property to change the color of the cursor bubble. In your theme change the textSelectionHandleColor to transparent . Like this.

Theme(
      data: Theme.of(context).copyWith(
        textSelectionHandleColor: Colors.transparent, 
      ),
