The convention is that implementation files are placed in the folder lib and package private files in the folder lib/src. For an app, the public file directly in lib is commonly main.dart and everything else models, screens, ... is located in lib/src.

For more information see package layout.

It is highly recommended that you only import files in lib or through packages, including local packages.

  dependencies:
    packageA:
      path: ../packageA/

I couldn't find the offical documentation for the following at all, so processed with caution.

It appears that library(.dart file) in lib cannot import files outside lib using a relative path. (You can import anything through relative path in other directories like test)

However, you can use absolute path to import file anywhere like this

import 'file:///Users/bob/weather/home.dart';
