How can I dismiss the on screen keyboard?

To summarize, this is a working solution for Flutter 1.17:

Wrap your Widget like this:

GestureDetector(
onTap: FocusScope.of(context).unfocus,
child: YourWidget(),
);

To dismiss the keyboard (1.7.8+hotfix.2 and above) just call the method below:

FocusScope.of(context).unfocus();

Once the **FocusScope.of(context).unfocus()** method already check if there is focus before dismiss the keyboard it's not needed to check it. But in case you need it just call another context method: `FocusScope.of(context).hasPrimaryFocus`

You can also declare a focusNode for you textfield and when you are done you can just call the unfocus method on that focusNode
and also dispose it

```dart
class MyHomePage extends StatefulWidget {
MyHomePageState createState() => new MyHomePageState();
}

class MyHomePageState extends State<MyHomePage> {
TextEditingController _controller = new TextEditingController();

/// declare focus
final FocusNode _titleFocus = FocusNode();

@override
void dispose() {
_titleFocus.dispose();
}

@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(),
floatingActionButton: new FloatingActionButton(
child: new Icon(Icons.send),
onPressed: () {
setState(() {
// send message
// dismiss on screen keyboard here

_titleFocus.unfocus();
_controller.clear();
});
},
),
body: new Container(
alignment: FractionalOffset.center,
padding: new EdgeInsets.all(20.0),
child: new TextFormField(
controller: _controller,
focusNode: _titleFocus,
decoration: new InputDecoration(labelText: 'Example Text'),
),
),
);
}
}
```

For me, the Listener above App widget is the best approach I've found:

```
Listener(
onPointerUp: (_) {
FocusScopeNode currentFocus = FocusScope.of(context);
if (!currentFocus.hasPrimaryFocus && currentFocus.focusedChild != null) {
currentFocus.focusedChild.unfocus();
}
},
child: MaterialApp(
title: 'Flutter Test App',
theme: theme,
...
),
)
```

This may simplify the case. Below code will work only if keyboard is open


if(FocusScope.of(context).isFirstFocus) {
FocusScope.of(context).requestFocus(new FocusNode());
}

FocusScope.of(context).unfocus() has a downside when using with filtered listView.
Apart from so many details and concisely, use keyboard_dismisser package in

will solve all the problems.

if you use CustomScrollView, just put,

```
keyboardDismissBehavior: ScrollViewKeyboardDismissBehavior.onDrag,
```

You can wrap your widget with "GestureDetector", then assign "FocusScope.of(context).unfocus()" to its onTap function

GestureDetector(
onTap: () => FocusScope.of(context).unfocus(),
child: child,
);

try using a TextEditingController.
at the begining,

final myController = TextEditingController();
@override
void dispose() {
// Clean up the controller when the widget is disposed.
myController.dispose();
super.dispose();
}


and in the on press event,

onPressed: () {
myController.clear();}
this will dismiss the keybord.

I have created this function to my base code, so far works well!!

void hideKeyword(BuildContext context) {
FocusScopeNode currentFocus = FocusScope.of(context);
if (!currentFocus.hasPrimaryFocus && currentFocus.focusedChild != null) {
currentFocus.focusedChild.unfocus();
}
}
