TextField doesn't loose focus on Android

[fralways]

When using Android simulator Nexus5X API 27 tapping on ('Android') button to dismiss keyboard doesn't remove focus from TextField thus preventing layout update after keyboard is dismissed. I have not found other way to listen for keyboard dismiss, and would expect that this is the correct way to do it. I guess this is an issue for all devices which have button to dismiss keyboard.

Steps to Reproduce

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  FocusNode _focusNode = FocusNode();

  @override
  void initState() {
    super.initState();

    _focusNode.addListener(() {
      print('Something happened');
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: TextField(
          focusNode: _focusNode,
          autofocus: true,
        ),
      ),
    );
  }
}

Using your code, I see that the FocusNode listener is not called when clicking the Android "down arrow" button to dismiss the keyboard, but it is called when clicking the checkmark in the keyboard. I'll try to figure out what the desired behavior is.

Besides the event, I think that visually keeping the cursor in the input after dismissing the keyboard is desired, though. I see the same behavior in native Android.

[fralways]

If keeping the cursor in the input in that case is desired then it explains why focus node doesn't push new event after keyboard dismiss and why this approach doesn't handle all use cases. Then I would need some other way to listen for keyboard change and I do not know any other listener for that. Something like UIKeyboardWillShowNotification and UIKeyboardWillHideNotification in iOS. Am I missing something? I would suggest to either expand listener for focus node so that we can listen for keyboard change events as well or to have some completely different listener for keyboard change events.

@gspencergoog This is the focus issue I mentioned to you. Will your work affect this at all?

[gspencergoog]

No, this won't be affected by my work. I don't know of a way to listen for the keyboard show/hide events at the moment, but that would be a good addition, especially since the platform can hide the keyboard independent of losing focus.

In latest stable (1.20.2) using given code sample, tapping on down arrow key keeps the cursor focused in textfield, while tapping on Done on keyboard removes the cursor focused. Tested on Android 8.1.0 device.

I have the same issue on Android. I show an overlay with a complex widget of search results for a search field. I would like to hide the overlay when the user dismisses the keyboard, however it can only be closed using the check icon on the keyboard. I have other controls on the page (slider) but those does not seem to grab the focus when used so I am stuck with an always open search box. Is there a workaround or any suggestion that I could implement? Thanks for the help.

I can reproduce the issue on the latest stable and the master channel, On tapping the Android back button the cursor still stays inside the TextField but on submitting (click the check icon on the keyboard) the TextField loses focus completely (cursor disappears). I verified the behavior in a few other apps like Instagram and youtube, Both seem to have the cursor on pressing the back button. While Whatsapp, does remove the cursor on pressing the back button, So Perhaps being able to configure this behavior would be ideal.

You could use MediaQuery.viewInsets for keyboard visibility
