channel.setMessageHandler error when building the example

[riverscuomo]

I'm unable to build the example. I'm on Flutter 3.0.5. I get the following error.

apps\plugins\flutter_cast_framework\android\src\main\java\com\gianlucaparadise\flutter_cast_framework\PlatformBridgeApis.java:1158: error: lambda expressions are not supported in -source 7
          channel.setMessageHandler((message, reply) -> {
                                                     ^
  (use -source 8 or higher to enable lambda expressions)
