Steps to Reproduce
code sample
import 'package:flutter/material.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/services.dart';
final Color darkBlue = Color.fromARGB(255, 18, 32, 47);
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
theme: ThemeData.dark().copyWith(scaffoldBackgroundColor: darkBlue),
debugShowCheckedModeBanner: false,
home: Scaffold(
body: Center(
child: MyWidget(),
),
),
);
}
}
class MyWidget extends StatelessWidget {
@override
Widget build(BuildContext context) {
return TextField(
autocorrect: false,
enableSuggestions: false,
keyboardType: TextInputType.emailAddress,
inputFormatters: [
FilteringTextInputFormatter.allow(
RegExp(r"""[a-zA-Z0-9\_\.\,\-\(\)\/\=\+\?\>\<\!\*\'\"\;\&\@\#\:\%\[\]\‘\\\$\{\}\^\|\~\`]+""")),
],
);
}
}
TextField with inputFormatters (for example, WhitelistingTextInputFormatter.digitsOnly) and some of keyboardTypes (phone, datetime, visiblePassword and number) work not as it expected. If i type not a digit (remember, we are using WhitelistingTextInputFormatter.digitsOnly inputFormatters), onChange fires twice and the last one will be with forbidden symbol in onChange text. With another keyboardType onChange fires only once and without "forbidden" symbol in the text (not sure if it even should fire).
Expected results: Forbidden symbols shouldn't be in the onChange text.
Actual results: onChange fires twice with forbidden symbol in the last change.
