raisedbutton’ is deprecated and shouldn’t be used

2 Answers. Show activity on this post. That means that the Widget is deprecated and it will be removed in future versions. You should replace those Widgets with others that aren’t deprecated.

First are obsolete classes. Quotes from the Flutter documentation: FlatButton, RaisedButton, and OutlineButton have been replaced by TextButton, ElevatedButton, and OutlinedButton respectively.

Disclamer: As of May 2021 the FlatButton class in flutter is deprecated . TextButton class should be used instead. The later class will eventually be removed from flutter SDK, so it is suggested to move to the newer class.
