MACOS touch bar show password text

[theotruvelot]

Hello, I'm writing a macOS app in flutter,
I make a password TextField, and in touch bar there is the password string.

my code :

final password = SizedBox(
      child: TextField(
        autocorrect: false,
        enableSuggestions: false,
        onSubmitted: (value) {
          if (emailController.text.isNotEmpty &&
              passwordController.text.isNotEmpty) {
            authBloc.add(
              LoginEvent(
                  email: emailController.text,
                  password: passwordController.text),
            );
          } else {
            ScaffoldMessenger.of(context).showSnackBar(
              SnackBar(
                backgroundColor: Constants.primaryColor,
                content: Text(
                  'Veuillez remplir tous les champs',
                  style: GoogleFonts.poppins(),
                ),
              ),
            );
          }
        },
        controller: passwordController,
        autofocus: false,
        obscureText: isObscure,
        decoration: InputDecoration(
          prefixIcon: const Icon(
            Icons.lock,
            color: Colors.grey,
            size: 20,
          ),
          suffixIcon: Padding(
            padding: const EdgeInsets.only(right: 8.0),
            child: IconButton(
              onPressed: () {
                setState(() {
                  isObscure = !isObscure;
                });
              },
              icon: isObscure
                  ? const Icon(Icons.visibility_off,
                      color: Colors.grey, size: 20)
                  : const Icon(Icons.visibility, color: Colors.grey, size: 20),
            ),
          ),
          hintText: 'Password',
          hintStyle: GoogleFonts.poppins(color: Colors.grey),
          contentPadding: const EdgeInsets.fromLTRB(20.0, 10.0, 20.0, 10.0),
          focusedBorder: OutlineInputBorder(
              borderRadius: BorderRadius.circular(32.0),
              borderSide:
                  const BorderSide(color: Constants.accentColor, width: 2)),
          border: OutlineInputBorder(
              borderRadius: BorderRadius.circular(32.0),
              borderSide:
                  const BorderSide(color: Constants.accentColor, width: 2)),
        ),
      ),
    );

@p2acoo Thanks for reporting this. This issue is reproducible on the latest stable and master channels with below minimal sample code.

Below is the demo when comparing Flutter app with macOS native app (using Secure Text Field view).

Flutter	macOS native

Also, this seems to be a regression issue since it works as expected on Flutter 3.0.5.

stable 3.7.1	master 3.8.0-2.0.pre.43	3.3.10	3.0.5
❌	❌	❌	✅

✅: No Issue ❌: Issue reproduced

Sample code (minimal and complete)

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> {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const Scaffold(
        body: Center(
          child: TextField(
            obscureText: true,
            enableSuggestions: false,
            autocorrect: false,
          ),
        ),
      ),
    );
  }
}

flutter doctor -v (stable and master)

I bisected this regression to flutter commit #106162
It is probably related to flutter/engine#33827

@knopp
It seems that putting the FlutterTextInputPlugin in the view hierarchy automatically create a link with the Mac Touch Bar.
Maybe there is a way to desactivate this link based on the TextField configuration?

[cbracken]

Yikes. Thanks for filing. @knopp's patch didn't introduce the bug so much as it revealed the existing bug. Nice catch. I'll get a fix out!
