How to separate suffixIcon for password visibility? If I press icon on field password it also does the same thing on field confirm password.
import 'package:flutter/material.dart';
void main() => runApp(const MyApp());
class MyApp extends StatefulWidget {
const MyApp({Key? key}) : super(key: key);
@override
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
bool isObsecure = false;
@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: Scaffold(
appBar: AppBar(
title: const Text('Text Form Field'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
TextFormField(
obscureText: isObsecure,
decoration: InputDecoration(
hintText: 'Password',
suffixIcon: IconButton(
onPressed: () {
setState(() {
isObsecure = !isObsecure;
});
},
icon: Icon(
isObsecure ? Icons.visibility_off : Icons.visibility,
),
),
),
),
TextFormField(
obscureText: isObsecure,
decoration: InputDecoration(
hintText: 'Confirm Password',
suffixIcon: IconButton(
onPressed: () {
setState(() {
isObsecure = !isObsecure;
});
},
icon: Icon(
isObsecure ? Icons.visibility_off : Icons.visibility,
),
),
),
),
],
),
),
),
);
}
}

you have to define 2 flags. 1 for password visibility and 1 for confirm:
import 'package:flutter/material.dart';
void main() => runApp(const MyApp());
class MyApp extends StatefulWidget {
const MyApp({Key? key}) : super(key: key);
@override
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
bool isObsecure = false;
bool isConfirmObsecure = false;
@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: Scaffold(
appBar: AppBar(
title: const Text('Text Form Field'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
TextFormField(
obscureText: isObsecure,
decoration: InputDecoration(
hintText: 'Password',
suffixIcon: IconButton(
onPressed: () {
setState(() {
isObsecure = !isObsecure;
});
},
icon: Icon(
isObsecure ? Icons.visibility_off : Icons.visibility,
),
),
),
),
TextFormField(
obscureText: isConfirmObsecure,
decoration: InputDecoration(
hintText: 'Confirm Password',
suffixIcon: IconButton(
onPressed: () {
setState(() {
isConfirmObsecure = !isConfirmObsecure;
});
},
icon: Icon(
isConfirmObsecure
? Icons.visibility_off
: Icons.visibility,
),
),
),
),
],
),
),
),
);
}
}
