cron_form_field

This CronFormField package is written in Dart for the Flutter. You can edit cron expressions with this form field in an alert dialog. This widget extends TextField to have more useful behavior. It supports both Standard and Quartz cron expressions with allowed and alternative values.

Usage

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  ...
  cron_form_field: "^0.7.0"

In your library add the following import:

import 'package:cron_form_field/cron_form_field.dart';

For help getting started with Flutter, view the online documentation.

Example

CronFormField(
  initialValue: '0 0 */3 ? * * *',
  // controller: _cronController,
  labelText: 'Schedule',
  onChanged: (val) => print(val),
  onSaved: (val) => print(val),
  // outputFormat: CronExpressionOutputFormat.AUTO
);

The result of val in onChanged, validator and onSaved will be a String.
