Flutter-LinearGradient的平滑过渡颜色 [英] Flutter - Smooth transition color for LinearGradient

问题描述

喂！

是否存在创建在起始色和ens颜色之间具有平滑过渡的LinearGradient的解决方案?

Is there a solution for creating a LinearGradient that has a smooth transition between start and ens color?

new Container(
        decoration: new BoxDecoration(
          gradient: new LinearGradient(
              colors: [
                Colors.black,
                Colors.grey,
              ],
            stops: [0.0, 1.0],
            begin: FractionalOffset.topCenter,
            end: FractionalOffset.bottomCenter,
            tileMode: TileMode.repeated
          )
        ),
)

推荐答案

似乎来自Android仿真器.在这种情况下，它将使用低质量的渲染器，以使其足够快地运行，尤其是在功能较弱的硬件上.在真实的设备上进行测试，您可能会看到更好的结果.我相信您也许还可以提高模拟器上的图形，但不能百分百确定这是否可以改善此问题.请参见此处.

It appears as though that may be from the Android Emulator. If that is the case, it uses a low-quality renderer so that it runs fast enough especially on less powerful hardware. Test it out on a real device and you'll likely see better results. I believe you may also be able to bump up the graphics on the emulator but not 100% sure if that would improve this. See here.

这就是Nexus 4与仿真器之间的渐变效果.

This is what the gradient looks like on a Nexus 4 vs the emulator.
