versionId property

  1. @override
Future<String> versionId
override

Returns an appropriate version ID for diagnostic purposes, which must not be null.

This doesn't have any specific format; it's solely for diagnostic purposes. The included sources return strings of the format 'source identifier: source version' indicating where the information comes from and which version of the source information has been loaded.

Implementation

@override
Future<String> get versionId => Future.sync(() => 'TZDB: 2018');
