Hướng dẫn cách sử dụng nút bấm (Button) trong Flutter
The FlatButton, RaisedButton and OutlineButton widgets have been replaced by TextButton, ElevatedButton, and OutlinedButton respectively. Each new button class has its own theme: TextButtonTheme, ElevatedButtonTheme, and OutlinedButtonTheme. The original ButtonTheme class is no longer used. The appearance of buttons is specified by a ButtonStyle object, instead of a large set of widget parameters and properties. This is roughly comparable to the way that the appearance of text is defined with a TextStyle object. The new button themes are also configured with a ButtonStyle object. A ButtonStyle is itself just a collection of visual properties. Many of these properties are defined with MaterialStateProperty, which means that their value can depend on the button’s state.
