onInit method

@override void onInit()

Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.

@override
void onInit() {
  super.onInit();

  textMessage = Get.arguments['caption'];
  // debugPrint("caption text received--> $textMessage");
  caption.text = textMessage;
  SchedulerBinding.instance
      .addPostFrameCallback((_) => filePath(Get.arguments['filePath']));
}
