copied to clipboard
MaterialApp(
title: 'Dropdown Alert Demo',
theme: ThemeData(

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';
copied to clipboard
AlertController.show("Title", "message here!", TypeAlert.success, payload);
copied to clipboard
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");
});
