Flutter Focus Watcher #

This widget is used to remove TextField focus if a tap occured somewhere else In order for this to work properly, it must be placed inside MaterialApp or WidgetsApp. This is necessary because this widget requires MediaQuery, which is supplied by those two.

The widget also keeps track of a keyboard space and moves the whole application up if a focused TextField gets obscured by the keyboard The only additional thing you need to do for it is to set your Scaffold's resizeToAvoidBottomInset to false (in case you use scaffold) and that's it. If you want to change the height of application lift, simply set your preferred value to the FocusWatcher's liftOffset variable. The default value is 15.0. This means the number of points above the keyboard's upper bound

Example #

It's very easy to use. You may add it as a library or simply copy flutter_focus_watcher.dart into your project. It doesn't have any external dependencies

Then simply do this. Notice that FocusWatcher is inside MaterialApp. That's because it inherits MediaQuery from that

IMPORTANT! You must wrap with the FocusWatcher every scaffold where you want this functionality

import 'package:flutter/material.dart';
import 'package:flutter_focus_watcher/flutter_focus_watcher.dart';

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

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
   Widget build(BuildContext context) {
      return MaterialApp(
        title: 'Demo app',
        theme: ThemeData(
          primarySwatch: Colors.blue,
        home: MyHomePage(title: 'Flutter Demo Home Page')

  Widget build(BuildContext context) {
    return FocusWatcher(
        child: Scaffold(
         // don't forget about this
         resizeToAvoidBottomInset: false,

And it will do the rest.

alt watcher

And here is how it handles the keyboard

alt keyboard

In case you want to exclude some widget from this workflow, simply wrap that widget with

Widget build(BuildContext context) {
    return IgnoreFocusWatcher(
      child: TextField("I will be ignored by FocusWatcher")

And this widget will be ignored by FocusWatcher

There may also be some cases when a TextField (like material text field) does not apply a RenderEditable or RenderParagraph thus making this plugin useless. You can simply fix it by wrapping the TextField in a ForceFocusWatcher() widget. That's it

Widget build(BuildContext context) {
    return ForceFocusWatcher(
      child: TextField("I'm forced to activate focus watcher")
