Flutter sdk 未找到。 build.gradle中的GradleException错误

Question

I am developing a flutter application and I am having certain errors. The flutter SDK location is rightly provided but it says that Flutter SDK not found.

The error is arising from the file build.gradle inside the android folder:

if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

I am even trying to change it but it says that "Cannot resolve symbol 'GradleExecption'". I am also having the same error in the AndroidManifest.xml file where I am specifying the "android:icon: drawable/app_logo.png" but it says that "Cannot resolve symbol 'drawable'".

Can someone help me with this please?

Answer 1

也许尝试运行 Flutter Doctor 看看它给了你什么，如果这没有产生任何结果，然后尝试检查 Flutter 的 PATH 是否正确

Answer 2

1 if (flutterRoot == null) { throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.") } cntrl+Alt+S then show settings window then search flutter you can see in under language and framework .Add flutter sdk path.

Here you verify the above path and restart the ide(Android Studio) path :.android/local.properties

2 I am also having the same error in the AndroidManifest.xml file where I am specifying the "android:icon: drawable/app_logo.png" but it says that "Cannot resolve symbol 'drawable'".

check your path string add @withdrawable eg: android:icon="@drawable/app_logo.png"

Answer 3

remove the keyword new from Gradle.it will work before: throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")

after: throw GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")

Answer 4

Try changing:

GradleException()

to:

FileNotFoundException()
