flutter What's the difference AppBarTheme "color" and "backgroundColor"?

color: Colors.transparent,

backgroundColor: Colors.transparent,

Color and background color have the same effect. What's the difference?

There is no difference, color is a deprecated value and you should use backgroundColor.

If you look at the code of the AppBarTheme you will read:


  /// This property is deprecated, please use [backgroundColor] instead.
  ///
  /// Obsolete property that overrides the default value of
  /// [AppBar.backgroundColor] in all descendant [AppBar] widgets.
  ///
  /// See also:
  ///
  ///  * [backgroundColor], which serves this same purpose
  ///    as this property, but has a name that's consistent with
  ///    [AppBar.backgroundColor].
  ///  * [AppBar.backwardsCompatibility], which forces [AppBar] to depend
  ///    on this obsolete property.
  @Deprecated(
    'This property is no longer used, please use backgroundColor instead. '
    'This feature was deprecated after v2.4.0-0.0.pre.',
  )
  Color? get color => backgroundColor;

  /// Overrides the default value of [AppBar.backgroundColor] in all
  /// descendant [AppBar] widgets.
  ///
  /// See also:
  ///
  ///  * [foregroundColor], which overrides the default value for
  ///    [AppBar.foregroundColor] in all descendant widgets.
  final Color? backgroundColor;

You can also see the code on the Flutter repo.

There is no difference between both of them, background value by default equals the color value. So, if you need custom app bar color on a specific page you can use the background-color
