can you help me ? I don't understand why Gradle gives me this error

CodePudding user response：

it says that the compiler cannot find FlatButton and RaisedButton maybe you forgot to import them.

CodePudding user response：

The FlatButton, RaisedButton and OutlineButton widgets have been replaced by TextButton, ElevatedButton, and OutlinedButton respectively. you can read the details

CodePudding user response：

Instead of FlatButton you can use TextButton.

FlatButton is removed in newer Flutter versions.
