fl_text_input_channel_new()

FlTextInputChannel* fl_text_input_channel_new	(	FlBinaryMessenger *	messenger,
		FlTextInputChannelVTable *	vtable,
		gpointer	user_data
	)

fl_text_input_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.textInput from the Flutter services library.

Returns: a new #FlTextInputChannel.
