How to import file from lib into file outside of lib in Flutter-CodePudding

I have customised a Flutter package and therefore it's outside of my lib folder.

Structure:

project_name
- lib
  - file.dart
- package
  - package_file.dart

I want to import file.dart into package_file.dart. How can I achieve this? Tried import 'package:project_name/lib/file.dart' but it says URI not exist.

CodePudding user response：

You should have pubspec.yaml in your package module and declare your project root file packages yaml's dependencies like this :

dependencies:

  ROOT_PROJECT_NAME:
    path: ../../ROOT_PROJECT_NAME
