After Flutter update some of Widgets are Deprecated.
You Used TextButton instead of FlatButton, FlatButton is deprecated by flutter.

CodePudding user response：
In TextButton, all your style should be inside the "style: ButtonStyle" like this:
TextButton(
style: ButtonStyle(
shape: MaterialStateProperty.all(
RoundedRectangleBorder(
side: const BorderSide(
color: Colors.black12,
width: 2,
style: BorderStyle.solid,
),
borderRadius: BorderRadius.circular(0.0),
),
),
),
child: Text(
"CLICK ME!",
style: const TextStyle(
fontSize: 30.0,
fontWeight: FontWeight.bold,
color: Colors.black,
),
),
onPressed: () {
debugPrint("Click Button pressed");
},
),
