Imitate fully qualified imports in live templates

[eEQK]

When evaluating a live template in java you can do this:

private static final org.apache.logging.log4j.Logger logger = org.apache.logging.log4j.LogManager.getLogger($CLASS_NAME$.class);$END$

IDE will add an import statement upon evaluation. So it will essentially become this but with imported dependencies:

private static final Logger logger = LogManager.getLogger($CLASS_NAME$.class);$END$

Unfortunately, in dart we don't have qualified imports, but we could do something simillar:

my_package/my_package.AppNavigator.of(context)

Will become this:

import 'package:my_package/my_package.dart';

AppNavigator.of(context)
