vdocipher_flutter

VdoCipher plugin for flutter apps.

This project is a Flutter plugin package, that will enable video playback functionality by delegating to respective native libraries based on the platform.

Note:

1. Please contact us at [e-mail] before using it in your application
2. IOS is not supported. Only Android support available. IOS support will be added in future.

Getting started

Run this command with Flutter:

$ flutter pub add vdocipher_flutter

This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):

dependencies:
  vdocipher_flutter: ^1.0.0-beta.4

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:vdocipher_flutter/vdocipher_flutter.dart';

Example

samples.dart

import 'package:vdocipher_flutter/vdocipher_flutter.dart';

const EmbedInfo SAMPLE_1 = EmbedInfo.streaming(
    otp: '20160313versASE313BlEe9YKEaDuju5J0XcX2Z03Hrvm5rzKScvuyojMSBZBxfZ',
    playbackInfo: 'eyJ2aWRlb0lkIjoiM2YyOWI1NDM0YTVjNjE1Y2RhMThiMTZhNjIzMmZkNzUifQ==',
    embedInfoOptions: EmbedInfoOptions(
        autoplay: true
    )
);

const EmbedInfo SAMPLE_2 = EmbedInfo.streaming(
    otp: '20160313versASE313CBS0f0mkwrNqTswuCYx7Lo41GpQ3r06wbx2WgOUASrQIgH',
    playbackInfo: 'eyJ2aWRlb0lkIjoiYTllYWUwOTZjZDg4NGRiYmEzNTE1M2VlNDJhNTA0YTgifQ=='
