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
