how to use it.
# pubspec.yaml
dependencies:
flutter:
sdk: flutter
flutter_dropdown_alert: <last-version>
just create a stack
widget and add dropdownalert()
inside materialapp
which should be in main.dart like this:
import 'package:flutter_dropdown_alert/dropdown_alert.dart';
materialapp(
title: 'dropdown alert demo',
theme: themedata(
visualdensity: visualdensity.adaptiveplatformdensity,
),
home: stack(
children: [
myhomepage(title: 'flutter dropdown alert demo'),
dropdownalert()
],
),
);
show alert anywhere, even inside bloc without widget:
next, import ‘alert_controller.dart’ into your dart code
import 'package:flutter_dropdown_alert/alert_controller.dart';
alertcontroller.show("title", "message here!", typealert.success, payload);
the payload
param is map<string, dynamic>
, this param is optional, should use to give data into the alert and get it when click on alert.
hide alert:
the alert will automatically hide, but if you use delaydismiss: 0
, it will freeze and not auto hide, you have to hide the alert by this code:
alertcontroller.hide();
listener when click on alert:
there are 2 ways to do that:
- using listener of controller, put this code inside
initstate()
of widget:
alertcontroller.ontablistener((map<string, dynamic> payload, typealert type) {
print("$payload - $type");
});
- using param
ontap
:
dropdownalert(ontap: (map<string, dynamic> payload, typealert type) {
print("$payload - $type");
},)
