Flutter初始化失败，java.lang.UnsatisfiedLinkError: dlopen失败：找不到库“libflutter.so”。

该应用在iOS上正常运行，但当我尝试在Android上运行时，会出现以下错误：

我尝试了这篇文章中提到的所有修复方法，但都没有解决问题。

我的情况变得更奇怪了。这个应用程序在模拟器和真机上都可以运行，但在发布版本中却产生了这个异常。 - happy-san

你可以做的最好的事情是：摆脱Flutter :-D。如果不可能，要知道Flutter是一个缓存地狱，你必须成为一个缓存大师......这个错误可以通过清除设备/模拟器上的应用程序缓存或卸载先前在设备/模拟器上安装的应用程序来修复。 - longi

我卸载并 清理项目（通过Android Studio）。然后再次运行，这对我有用。

卸载模拟器上的应用程序并重新启动模拟器，这对我有所帮助。

我之前为了缩短构建时间而删除了x86_64构建，导致出现了这个错误。如果删除它，模拟器将无法正常运行。

在android\app\build.gradle文件中。

android {
    buildTypes {
        release {
            ndk {
                // The line below only builds arm64-v8a 
                abiFilters  'arm64-v8a' // This breaks running the app in the emulator
                abiFilters 'armeabi-v7a','arm64-v8a','x86_64' // this includes all build targets 
                

            }
        }
    }
}

删除Flutter文件夹中的.gradle文件。然后运行应用程序，它将需要一些时间来下载新的gradle，当下载完成后，应用程序将成功运行。
