每当我尝试使用"flutter run -v"运行Flutter应用程序时，我会遇到以下错误。如果我不使用终端而是直接点击运行按钮，则gradle任务一直在运行，什么也没有发生。
我尝试过：
  1. 更改gradle.properties中的语句：org.gradle.jvmargs=-Xmx1536m => org.gradle.jvmargs:-Xmx1024m
  2. 删除".gradle"文件
  3. 重启笔记本电脑
我该怎么办？

你的电脑内存不足。我建议你切换到VSCode，并将内存升级至至少8GB。 - CoderUni
@Uni，我的内存是8GB（可用7.71GB），在使用VSCode时，它会弹出一个警告窗口，提示Flutter运行不再响应。 - salma.m
很奇怪。你能发一下flutter run --verbose的输出吗？ - CoderUni

问题在于OpenJDK平台二进制文件会打开很多实例，耗费了我的内存。我从这个问题中了解到此问题，并且这个答案建议关闭Hotspot功能，这样就解决了问题。有时候重新启动电脑也可能有效，但并不一定适用于所有情况。
我不知道Hotspot是如何引起问题的，或者它与OpenJDK有什么关联，如果有人能解释一下，请在评论中说明。
是的！它也对我起作用了... - Amisha Kirti

请始终将错误日志作为文本而不是图像发布。
1- 运行flutter clean，然后重新构建。
2- 您是在模拟器还是物理设备上运行它？
3- 如果是在模拟器上，请增加该设备的虚拟内存。更好的方法是删除模拟器并创建一个新的。
4- 如果仍然不起作用，请运行flutter upgrade。
5- 您能否将文件构建为APK？换句话说，不要在设备上运行？
6- 请发布flutter build apk -v的输出。
我正在物理设备上运行它。 - salma.m
我正在使用Windows 10。 - salma.m
你的设备重新启动有帮助吗？ - Huthaifa Muayyad
@salma.m 这意味着进展。flutter build apk -v 的输出结果一样吗？你构建了多久了？ - Huthaifa Muayyad

我已经尝试了以下解决方案，这些方案适用于所有情况：

1. Windows Bug > 这是一个非常普遍的问题，由此BUG引起，请在运行应用程序之前从设置中关闭移动热点。

2. 尝试关闭正在运行的额外软件，如果需要，关闭Chrome，使缓存无效并重新启动Android Studio。然后执行Flutter Clean、Flutter Pub Get和Run App。

3. 尝试从android文件夹中删除.gradle文件夹，使缓存无效并重新启动Android Studio，等待索引，然后开始构建应用程序。

4. 如果以上方法都不起作用，那么只需编辑gradle.properties文件，然后：

找到这一行：org.gradle.jvmargs=-Xmx1536M

将其替换为：org.gradle.jvmargs=-Xmx1024M
