Answer 1

当你调用PlacesAutocomplete.show将mode设置为Mode.overlay
时，包支持Mode.overlay

代码片段

body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
_buildDropdownMenu(),
RaisedButton(
onPressed: _handlePressButton,
child: Text("Search places"),
),
...
Widget _buildDropdownMenu() => DropdownButton(  
value: _mode,
items: <DropdownMenuItem<Mode>>[
DropdownMenuItem<Mode>(
child: Text("Overlay"),
value: Mode.overlay,
),
DropdownMenuItem<Mode>(
child: Text("Fullscreen"),
value: Mode.fullscreen,
),
],
onChanged: (m) {
setState(() {
_mode = m;
});
},
);
...   
Future<void> _handlePressButton() async {
// show input autocomplete with selected mode
// then get the Prediction selected
Prediction p = await PlacesAutocomplete.show(
context: context,
apiKey: kGoogleApiKey,
onError: onError,
mode: _mode,
language: "fr",
components: [Component(Component.country, "fr")],
);
displayPrediction(p, homeScaffoldKey.currentState);
}
