FlBinaryMessenger:

#FlBinaryMessenger is an object that allows sending and receiving of platform messages with an #FlEngine. FlBinaryMessengerResponseHandle:

#FlBinaryMessengerResponseHandle is an object used to send responses with. fl_binary_messenger_set_platform_message_handler: @binary_messenger: an #FlBinaryMessenger. @channel: channel to listen on. @handler: (allow-none): function to call when a message is received on this channel or NULL to disable a handler @user_data: (closure): user data to pass to @handler. @destroy_notify: (allow-none): a function which gets called to free @user_data, or NULL.

Sets the function called when a platform message is received on the given channel. See FlBinaryMessengerMessageHandler for details on how to respond to messages.

The handler is removed if the channel is closed or is replaced by another handler, set @destroy_notify if you want to detect this.

fl_binary_messenger_set_warns_on_channel_overflow: @messenger: an #FlBinaryMessenger. @channel: channel to be allowed to overflow silently. @warns: when false, the channel is expected to overflow and warning messages will not be shown.

Sends a message to the control channel asking to allow or disallow a channel to overflow silently.

FlBinaryMessengerMessageHandler: @messenger: an #FlBinaryMessenger. @channel: channel message received on. @message: message content received from Dart. @response_handle: a handle to respond to the message with. @user_data: (closure): data provided when registering this handler.

Function called when platform messages are received. Call fl_binary_messenger_send_response() to respond to this message. If the response is not occurring in this callback take a reference to @response_handle and release that once it has been responded to. Failing to respond before the last reference to @response_handle is dropped is a programming error.
