FlKeyboardChannel* fl_keyboard_channel_new | ( | FlBinaryMessenger * | messenger,

fl_keyboard_channel_new: @messenger: an #FlBinaryMessenger @vtable: callbacks for incoming method calls. @user_data: data to pass in callbacks.

Creates a new channel that implements SystemChannels.keyboard from the Flutter services library.

Returns: a new #FlKeyboardChannel
