Question

这是我在调试控制台中得到的大部分内容，当我运行最初的flutter应用程序，与flutter一起。这看起来不正常。我应该怎么做才能解决这个问题？

假设你没有碰过启动代码，跳过的帧数随着你的运行而下降的事实告诉我，这是在你的机器上运行模拟器的自然副产品。一般来说，< 这些消息中的100跳帧可以被安全地忽略--这意味着你的电脑在实时运行模拟器时遇到了困难。

将你的实体Android设备放入 调试模式 然后用电缆连接，然后选择该设备作为你的构建目标。如果你在手机上运行应用，你还会被跳帧吗？如果你运行的是任何一种现代Android手机，你一般不会。

Android模拟器需要大量的处理能力来运行。大多数人 普遍认为 在物理设备上调试比通过仿真器调试要快好几倍。

我曾经遇到过同样的问题。当我通过指向发布模式运行应用程序时，问题就解决了。请试一试 flutter run --release 而不是 flutter run
