usage_trigger

A Flutter package that enables triggering asynchronous actions based on usage conditions, such as initial delay, minimum event count, frequency, and dependencies on other triggers. It provides the UsageTrigger widget for seamless integration into Flutter UIs and the triggerWhenDue function for flexible trigger logic.

Getting started

Requirements

Flutter SDK: >= 3.0.0
Dart: >= 2.17.0
Dependencies: shared_preferences, synchronized

API Overview

UsageTrigger: A StatefulWidget that renders a child widget and calls triggerWhenDue on initialization.
triggerWhenDue: Triggers asynchronous actions based on usage conditions (initial delay, minimum events, frequency).

Usage

Using the triggerWhenDue function

import 'package:usage_trigger/trigger_when_due.dart';

void example() async {
  await triggerWhenDue(
    id: 'my_feature',
    initialDelay: Duration(days: 1),
    minEvents: 5,
    frequency: Duration(hours: 24),
    dependencyConditions: [
      DependencyCondition(
        dependentTriggerId: 'other_feature',
        cooldownPeriod: Duration(hours: 12),
        mustHaveSucceeded: true,
      ),
    ],
    onTrigger: () async {
      // Your action here
      print('Trigger activated!');
      return true; // Return true on success
    },
  );
}

Using the UsageTrigger

import 'package:flutter/material.dart';
import 'package:usage_trigger/trigger_when_due.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: TriggerPoint(
          id: 'example_trigger',
          initialDelay: Duration(seconds: 5),
          minEvents: 3,
          frequency: Duration(minutes: 2),
          dependencyConditions: [
            DependencyCondition(
              dependentTriggerId: 'another_trigger',
              cooldownPeriod: Duration(minutes: 1),
              mustHaveSucceeded: false,
            ),
          ],
          onTrigger: () async {
            print('Action triggered!');
            return true;
          },
          child: Center(child: Text('Hello, World!')),
        ),
      ),
    );
  }
}
