How to reference another file in Dart?

Question

I know you can use the library, import and even #import, but which is correct?

I have got two files, MainClass.dart

Answer 1

Although i am answering very late, but the answer may help new developer.

Always use pubspec.yaml file in your dart package(application/library).

once you run pub get command it will add your local library in the dependencies list in .packages file.

Consider i have following project structure.

To refer to the content of greeting.dart in my main.dart file i should add the library as below

import 'package:my_project_name/greeting.dart'

Once imported we can use the content of greeting.dart file in our main.dart file. Note: we have not used the actual path as you can see 'lib' directory is missing.
