Rebuild ListView after operation on List Flutter - flutter

Question

I am trying to refresh the list of recipes after i delete one item and i have tried using SetState but I've got no result. I think the issue is that i get to this screen after making a GET call and that call is not executed again after deleting the item. What can I do?
void _pushRecipesByTypeScreen(String type) async {
var recipes = await entityApi.getRecipesByType(type);
Navigator.of(context).push(new MaterialPageRoute(builder: (context) {
return new Scaffold(
appBar: new AppBar(title: new Text(type)),
body: ListView.builder(
itemCount: recipes.length,
itemBuilder: (context, index) {
final item = recipes[index];
return _buildEntityItem2(item);
})
);
}));
}
Widget _buildEntityItem2(Entity entity) {
return ListTile(
title: Text(entity.name),
onTap: () => _pushDeleteScreen(entity),
);
}
void _pushDeleteScreen(Entity entity) {
showDialog(
context: context,
builder: (BuildContext context) {
return new AlertDialog(
title: new Text('Delete "${entity.name}"?'),
actions: <Widget>[
new FlatButton(
child: new Text('CANCEL'),
onPressed: () => Navigator.of(context).pop()),
new FlatButton(
child: new Text('CONFIRM'),
onPressed: () {
_removeEntityItem(entity);
setState(() {});
Navigator.of(context).pop();
})
]);
});
}
void _removeEntityItem(Entity entity) async {
if (await connectivity.checkConnectivity() != ConnectivityResult.none) {
bool success = await entityApi.deleteEntity(entity);
if (success) {
setState(() {});
}
}
}

The setstate should be used outside of dialog for it to reload your listview
void _pushRecipesByTypeScreen(String type) async {
var recipes = await entityApi.getRecipesByType(type);
Navigator.of(context).push(new MaterialPageRoute(builder: (context) {
return new Scaffold(
appBar: new AppBar(title: new Text(type)),
body: ListView.builder(
itemCount: recipes.length,
itemBuilder: (context, index) {
final item = recipes[index];
return _buildEntityItem2(item);
})
);
}));
}
Widget _buildEntityItem2(Entity entity) {
return ListTile(
title: Text(entity.name),
onTap: () async {
if(await _pushDeleteScreen(entity)) {
await _removeEntityItem(entity); //await until this completes
setState(() {});
}
}
);
}
Future<bool> _pushDeleteScreen(Entity entity) {
return showDialog(
context: context,
builder: (BuildContext context) {
return new AlertDialog(
title: new Text('Delete "${entity.name}"?'),
actions: <Widget>[
new FlatButton(
child: new Text('CANCEL'),
onPressed: () => Navigator.of(context).pop(false)),
new FlatButton(
child: new Text('CONFIRM'),
onPressed: () {
Navigator.of(context).pop(true);
})
]);
});
}
// make this return future
Future<void> _removeEntityItem(Entity entity) async {
if (await connectivity.checkConnectivity() != ConnectivityResult.none) {
bool success = await entityApi.deleteEntity(entity);
if (success) {
setState(() {});
}
}
}
