Cannot Resolve Symbol 'Properties' on Android Studio

Question

There are two errors in my Android Studio right now. In the app level build.gradle folder, the line

def localProperties = new Properties()

shows error Cannot Resolve Symbol 'Properties' and on

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

it says Cannot Resolve Symbol GradleException, What should I do to solve these two errors?

Solution

Set Project SDK to Android API Platform version 29 (or the latest version, 30), like so:

Step 1:

defaultConfig {
    ...
    minSdkVersion 16
    targetSdkVersion 30
}

Step 2:

update GradleException() to FileNotFoundException()

Step 3:
