Cron Expression Parser API - Dart/Flutter Client

Cron Expression Parser decodes 5-field and 6-field cron expressions into human-readable schedules. Pass any cron string to verify syntax, read plain-language timing explanations, and get the next five execution timestamps.

This is the Dart/Flutter client for the Cron Expression Parser API.

Installation

Add this to your pubspec.yaml:

dependencies:
  apiverve_cronparser: ^1.2.2

Then run:

dart pub get
# or for Flutter
flutter pub get

Usage

import 'package:apiverve_cronparser/apiverve_cronparser.dart';

void main() async {
  final client = CronparserClient('YOUR_API_KEY');

  try {
    final response = await client.execute({
      'expression': '0 9 * * 1-5'
    });

    print('Status: ${response.status}');
    print('Data: ${response.data}');
  } catch (e) {
    print('Error: $e');
  }
}
