Widget buildSampleUsingKeyboardAwareWidget() {
return Center(
child: Column(
children: <Widget>[
TextField(),
TextField(
keyboardType: TextInputType.number,
),
TextField(),
SizedBox(
height: 30,
),
KeyboardAware(
builder: (context, keyboardConfig) {
return Text('is keyboard open: ${keyboardConfig.isKeyboardOpen}\n'
'Height: ${keyboardConfig.keyboardHeight}');
},
),
],
),
);
}
