Answer 1

For me just deleting new before Properties and GradleException it have solved it.

• Flutter version 1.21.0-10.0.pre.55 | Master Channel |
• Dart version 2.10.0 (build 2.10.0-11.0.dev)
• Android Studio 4.0.1

here is first lines in build.gradle 'contains changes'

def localProperties = Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

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