A dropdown alert package for flutter

Dropdown alert will help to notify to user when you call api success, error or something like that. It's will similar with push notification but you can custom more than that. You can show alert at anywhere without widget.

Demo

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");
             },)
