处理点按内容列表项目图像（Flutter 移动端应用开发实践）

To interact with an image in a content list to open the corresponding page, first figure out how to tap the image.
Overlay the content image widget with a Flutter-provided Ink widget.
Place these widgets within a Stack widget.
The description covers using a PostMedia widget within the Stack.
The PostMedia widget is replaced with a post this item dia.
In the annotation method, define the post decide media using a Stack.
Add the previously mentioned PostMedia to the children of the stack followed by a PostMiezeMediaMask.
Define the mask for the post list immediately above using a Fill constructor to create it.
Set the child of the Material widget to be transparent using Colors.transparent.
For the InkWell widget, set its splash color to Colors.deepPurpleAccent with an opacity of 0.3, which creates a mustard-like effect on tap.
Add an onTap event handler inside the widget to output text "on tap post insides" in the console when the content image is tapped.
