Hi @agordeev
could you please provide a complete minimal reproducible code sample? such that I can copy and run

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () {
        FocusScopeNode currentFocus = FocusScope.of(context);
        if (!currentFocus.hasPrimaryFocus) {
          currentFocus.unfocus();
        }
      },
      child: Scaffold(
        appBar: AppBar(title: Text('title')),
        body: Center(child: TextField()),
        drawer: Drawer(
          child: ListView(
            padding: EdgeInsets.zero,
            children: <Widget>[
              DrawerHeader(
                child: Text('Drawer Header'),
                decoration: BoxDecoration(
                  color: Colors.blue,
                ),
              ),
              ListTile(
                title: Text('Item 1'),
                onTap: () {
                  Navigator.pop(context);
                },
              ),
              ListTile(
                title: Text('Item 2'),
                onTap: () {
                  Navigator.pop(context);
                },
              ),
            ],
          ),
        ),
      ),
    );
  }
}

I can't reproduce with it

Hi @agordeev
Are you still experiencing this issue?
Thank you

Yes, it's still reproducible on 1.17.0-3.3.pre. It's not reproducible with the code snippet above though.

@agordeev
provide please a complete minimal reproducible code sample

@VladyslavBondarenko this issue is not my priority at this moment, so I'm going to close it for now.

@agordeev I am facing similar issue.

The same issue happened to me.
It only happens when you close the keyboard shown for a Texfield with
FocusScope.of(context).unfocus();
This issue needs a fix and should not be closed.

Reproduces with current stable 1.17.1 (1.17.0 as well), beta 1.18.0-11.1.pre, dev 1.19.0-1.0.pre.
But not with previous stable v1.12.13+hotfix.9.

Code sample from #54277 (comment)

I bisected this and traced the cause to this PR, which makes sense.

I'll try and track down the exact cause of the regression.

Actually, it looks like the example code has a bug in it, and the PR (which corrected some buggy behavior in focus handling) has tickled that bug:

The corrected code should look like this:

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () {
        final FocusScopeNode currentScope = FocusScope.of(context);
        if (!currentScope.hasPrimaryFocus && currentScope.hasFocus) {
          FocusManager.instance.primaryFocus.unfocus();
        }
      },
      child: Scaffold(
        appBar: AppBar(title: const Text('title')),
        body: const Center(child: TextField()),
        drawer: Drawer(
          child: ListView(
            padding: EdgeInsets.zero,
            children: <Widget>[
              const DrawerHeader(
                child: Text('Drawer Header'),
                decoration: BoxDecoration(
                  color: Colors.blue,
                ),
              ),
              ListTile(
                title: const Text('Item 1'),
                onTap: () {
                  Navigator.pop(context);
                },
              ),
              ListTile(
                title: const Text('Item 2'),
                onTap: () {
                  Navigator.pop(context);
                },
              ),
            ],
          ),
        ),
      ),
    );
  }
}

Where instead of:

      onTap: () {
        FocusScopeNode currentFocus = FocusScope.of(context);
        if (!currentFocus.hasPrimaryFocus) {
          currentFocus.unfocus();
        }
      },

The code should be:

      onTap: () {
        final FocusScopeNode currentScope = FocusScope.of(context);
        if (!currentScope.hasPrimaryFocus && currentScope.hasFocus) {
          FocusManager.instance.primaryFocus.unfocus();
        }
      },

The original version gets the scope of the current context (which is the modal scope for the navigator's overlay), and then tells the scope to unfocus itself only if it does not have primary focus. Which, if the text field doesn't have focus, the scope does have focus, so it doesn't call unfocus at all then.

If the text field does have focus, then the code does call unfocus on the scope, which hands the focus to its parent scope, which is the navigator scope. Then, when the navigator pushes the drawer route, it tries to focus its own scope, but since we've just focused the navigator's scope, and the "first focus" of that scope is still the child scope, and its first focus is the editable text, the editable text gets focus again, raising the keyboard.

My recommendation above will instead only unfocus the primary focus if it is on a descendant of the current scope, but won't unfocus the scope itself, so it doesn't hand focus to the navigator's scope.

The bug in the example is that it calls unfocus on itself: it should call unfocus on the primaryFocus.

I'm going to close this issue, since it appears that #54277 (comment) explains how to use correctly use the unfocus API and avoid the problem.

This issue still happens

Flutter (Channel stable, 2.2.1, on Mac OS X 10.15.6 19G2021 darwin-x64,
    locale en-PH)

I Tried adding the code from #54277 (comment) before opening the Drawer but it doesnt work

@HansMuller any advice?

@basilmariano, as @gspencergoog explained, this worked for me:

onTap: () {
        final FocusScopeNode currentScope = FocusScope.of(context);
        if (!currentScope.hasPrimaryFocus && currentScope.hasFocus) {
          FocusManager.instance.primaryFocus.unfocus();
        }
      },
