Everything is formatted with `dart format` (no flags) and linted with `dart analyze` ([see rules](analysis_options.yaml)). Both are enforced by the CI.
Strings such as "_About one hour ago_" or "_~1h_" are localizable. We inherit a set of ready translations from [github.com/andresaraujo/timeago.dart/messages](https://github.com/andresaraujo/timeago.dart/tree/master/timeago/lib/src/messages) and provide our own in [lib/l10n/timeago](./lib/l10n/timeago).
To contribute time ago strings please send a PR containing a class that implements `timeago.LookupMessages`. Place it under [lib/l10n/timeago](./lib/l10n/timeago) with an appropriate name (locale tag) and finally register it in [main_common.dart](./lib/main_common.dart) in the `_setupTimeago` function. Each locale can have a normal (for example "_About one hour ago_") and a short (for example "_~1h_") variant, there are registered separately.
Lemmur is written in Dart using [Flutter](https://flutter.dev/docs). To communicate with Lemmy instances [lemmy_api_client](https://github.com/LemmurOrg/lemmy_api_client) is used.
[`MobX`](https://github.com/mobxjs/mobx.dart) + [Provider](https://github.com/rrousselGit/provider) is used for global state management, [flutter_hooks](https://github.com/rrousselGit/flutter_hooks) is used for local (widget-level) state management. `StatefulWidget`s are avoided all together and any state logic reuse is moved to a [custom hook](./lib/hooks).
LAC (Lemmy API Client) is used to communicate with Lemmy backends, more information can be found [here](https://github.com/LemmurOrg/lemmy_api_client).
