Complete notices
The application contains complete copyright notices and licence text for its shipped Flutter, Dart, engine, graphics, text, image, and Android components. They are available offline at Settings > About & legal > Open-source software > View all licence notices.
The list is long because large runtime components contain many separately attributed source files. The audited release bundle contained 86 component labels and approximately 1,610 notice sections before ExpenT's additional Android licence entry. No GPL or AGPL strong-copyleft licence was identified.
