fl_method_channel_respond()

G_BEGIN_DECLS gboolean fl_method_channel_respond	(	FlMethodChannel *	channel,
		FlBinaryMessengerResponseHandle *	response_handle,
		FlMethodResponse *	response,
		GError **	error
	)

fl_method_channel_respond: @channel: an #FlMethodChannel. @response_handle: an #FlBinaryMessengerResponseHandle. @response: an #FlMethodResponse. @error: (allow-none): #GError location to store the error occurring, or NULL to ignore.

Responds to a method call.

Returns: TRUE on success.
