这是我尝试过的：

body: Container(
          height: MediaQuery.of(context).size.height,
         width: MediaQuery.of(context).size.width,
          decoration: BoxDecoration(
            gradient:
            LinearGradient(colors: [Color(0xFFc2e59c), Color(0xFF64b3f4)]),
          )

我也尝试过不指定宽度和高度，但最终结果始终是一个不会完全填充主体的渐变 -

我正在使用flutter_native_splash包。我该如何修复这个错误？

Pubspec.yaml -

  cupertino_icons:\n\ndev_dependencies:\n  flutter_test:\n    sdk: flutter\n\nflutter_native_splash:\n image: assets/splash.png\n color: \xe2\x80\x9c6a1b9a\xe2\x80\x9d\n android: true\n fill: true\n\n# For information on the generic Dart part of this file, see the\n# following page: https://dart.dev/tools/pub/pubspec\n\n# The following section is specific to Flutter.\nflutter:\n

错误：
