为桌面上的 flutter 禁用高 DPI 缩放

Question

是否可以禁用 flutter 应用程序的高 dpi 缩放？我的布局效果很好，但是当比例因子设置得非常高时，应用程序变得很小。

或者至少有一种方法可以考虑缩放？

Answer 1

我现在正在使用 responsive framework 包。这为我解决了设置 defaultScale: true 时的缩放问题。添加断点时可以自定义行为。

我正在 MaterialApp.OnGenerateRoute:

中使用它

PageRouteBuilder switchScreen (Widget screen) =>
  PageRouteBuilder(
    pageBuilder: (_, __, ___) => ResponsiveWrapper.builder(
      screen,
      defaultScale: true,
      breakpoints: [
        const ResponsiveBreakpoint.resize(450, name: MOBILE),
        const ResponsiveBreakpoint.autoScale(800, name: TABLET),
        const ResponsiveBreakpoint.autoScale(1000, name: TABLET),
        const ResponsiveBreakpoint.resize(1200, name: DESKTOP),
        const ResponsiveBreakpoint.autoScale(2460, name: "4K"),
      ],
    ),
    settings: settings,
    transitionsBuilder: (_, a, __, c) =>
      FadeTransition(opacity: a, child: c)
  )
...
