Flutter Cast Framework

Overview

Flutter Cast Framework is a POC of a flutter plugin that lets you use Chromecast API in a flutter app.

Exposed APIs

Currently only the following APIs are integrated:

Android:
- Cast State
- Session state
- Send custom message
- Listen to received custom messages
- Cast Button
- Chromecast connection
iOS:
- Not implemented yet

Setup

Add Dependency

Clone this repo and add the following piece of code to your app's pubspec

dependencies:
  flutter_cast_framework:
    path: ../flutter_cast_framework/ # the path depends on where you cloned this repo

Android Setup

1. Create `CastOptionsProvider`

Add the following class to your Android project:

import android.content.Context
import com.google.android.gms.cast.framework.CastOptions
import com.google.android.gms.cast.framework.OptionsProvider
import com.google.android.gms.cast.framework.SessionProvider

class CastOptionsProvider : OptionsProvider {
    override fun getCastOptions(context: Context): CastOptions {
        return CastOptions.Builder()
                .setReceiverApplicationId("4F8B3483")
                .build()
    }

    override fun getAdditionalSessionProviders(context: Context): List<SessionProvider>? {
        return null
    }
}

2. Load `CastOptionsProvider`

Add the following entry in the AndroidManifest.xml file under the <application> tag to reference the CastOptionsProvider class:

<application>
    <meta-data
        android:name="com.google.android.gms.cast.framework.OPTIONS_PROVIDER_CLASS_NAME"
        android:value="com.gianlucaparadise.flutter_cast_framework_example.CastOptionsProvider" />
</application>

3. Theme

Make sure that your application and your activity are using an AppCompat theme (as stated here).

Tech notes

I used this project to test the capabilities of the following technologies:

Chromecast API (Sender - Android SDK)
Flutter
Flutter custom platform-specific code
