Dart by Example: Libraries

libraries are imported using the import keyword:

  1. // app.dart
  3. library app;
  5. import 'utils.dart';
  7. main() {
  8.   print(shout('Welcome'));
  9.   print(whisper('Welcome'));
  10. }
  11.  

libraries can be split into parts using the part and part of syntax:

  1. // utils.dart
  3. library utils;
  5. part 'whisper.dart';
  7. String shout(String inp) => inp.toUpperCase() + '!!!';
  8.  
  1. // whisper.dart
  3. part of utils;
  5. String whisper(String inp) => inp.toLowerCase() + '...';
  6.  
  1. $ app.dart
  2. WELCOME!!!
  3. welcome...
