Flutter 2.0 - 按下时如何更改 Textbutton 启动颜色

Question

FlatButton is deprecated and shouldn't be used. Used TextButton instead.

On my previous FlatButton widget, i was able to changed the splash color when on pressed. But now I'm using TextButton widget, how can i changed its color the efficient way on the MaterialApp ThemeData or directly on the TextButton widget.

Currenly this is my TextButton

TextButton(
  style: TextButton.styleFrom(
    primary: Colors.red,
    textStyle: TextStyle(
      color: Colors.black45,
      fontFamily: "Courier Prime",
    ),
    backgroundColor: Colors.transparent,
  ),
  onPressed: () {},
  child: Text(
    "Student",
    style: TextStyle(fontWeight: FontWeight.bold),
  ),
),

overlayColor is used to indicate that the button is focused, hovered, or pressed. But I cant find this overlayColor

Answer 1

First keep in mind that the primary property on a TextButton sets the colour of its text and icon. It does not change the ripple color. Secondly in Textbutton there is no direct property to change splash color. So if you want to change splash color to transparent you can do it like this.

TextButton(
  style: ButtonStyle(
    overlayColor: MaterialStateProperty.all(Colors.________),
  ),
)

Answer 2

TextButton(            
 style: ButtonStyle(
  overlayColor: MaterialStateColor.resolveWith((states) => Colors.red),
  ),
 child: ..., 
)

reference to Flutter TextButton splashColor property

You can change Splash color like this:

            Theme(
              data: ThemeData(
                splashColor: Colors.red,
                highlightColor: Colors.black.withOpacity(.5),
              ),
              child: ListTile(
                  title: Text(
                    "New theme splash",
                    textAlign: TextAlign.center,
                  ),
                  onTap: () {}),
            ),
