[jishnurajm]

I enabled flutter support and , SDK path is correct in local.properties . But it shows error message .

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.")
}

I tried with change the path in local.properties , restarting the ide , etc .. but nothing works . Will you please help me with this ( os ubuntu )
