Answer 1

You call remove() on the OverlayEntry itself.
This could be one way of doing it:
OverlayEntry _buildOverlayFeedback(BuildContext context, String tituloEvento) {
OverlayEntry entry;
entry = OverlayEntry(
builder: (context) => Material(
child: Container(
width: double.infinity,
height: double.infinity,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Column(
children: <Widget>[
ListTile(
leading: Icon(Icons.sentiment_dissatisfied),
title: Text('No me ha gustado'),
onTap: () {
entry.remove();
},
),
ListTile(
leading: Icon(Icons.sentiment_very_satisfied),
title: Text('Muy bien'),
onTap: () {}),
],
),
],
),
),
),
);
return entry;
}

For those of you who are trying to figure out how to do this with FCM onMessage with Navigator.of(context).overlay.insert(entry) - chemamolins' answer works, you just have to adapt it slightly. Here's a similar example to get you started:
onMessage: (Map<String, dynamic> message) async {
OverlayEntry entry;
entry = OverlayEntry(builder: (context) {
return GestureDetector(
onTap: entry.remove,
child: SafeArea(
child: Align(
alignment: Alignment.topCenter,
child: Material(
type: MaterialType.transparency,
child: Container(
decoration: BoxDecoration(color: Colors.white),
width: double.infinity,
height: 60,
child: Column(
children: <Widget>[
Text(message['notification']['title']),
Text(message['notification']['body']),
],
),
),
),
),
),
);
});
Navigator.of(context).overlay.insert(entry);
},
And onTap will close out the OverlayEntry.
