如何在flutter中增加AssetImage中的图像大小？

Image(
  image: AssetImage('assets/images/my_image.png'),
),

Image(
  image: AssetImage('assets/images/my_image.png'),
  width: 200, // 设置宽度为200像素
  height: 200, // 设置高度为200像素
),

final screenWidth = MediaQuery.of(context).size.width;
final screenHeight = MediaQuery.of(context).size.height;

Image(
  image: AssetImage('assets/images/my_image.png'),
  width: screenWidth * 0.5, // 设置宽度为屏幕宽度的一半
  height: screenHeight * 0.5, // 设置高度为屏幕高度的一半
),
