load method

Future<void> load(BuildContext context, { bool force = false, })

Reads the library from the store. The first time a user allowed to manage it opens it, the defaults of options are stored once.

Implementation

Future<void> load(BuildContext context, {bool force = false}) async {
  if (_loading || (_loaded && !force)) return;
  _loading = true;
  _error = null;
  notifyListeners();
  // Built before the first await, while the context is surely valid.
  final templates =
      options.defaultTemplates?.call(context) ?? const <PrintTemplate>[];
  final categories =
      options.defaultCategories?.call(context) ?? const <PrintCategory>[];
  final paperFormats = options.loadDefaultPaperFormats
      ? PaperFormatDefaults.all(context.reportL10n)
      : const <PaperFormat>[];
  try {
    var library = await store.load();
    if (!library.defaultsLoaded && library.canManage) {
      library = await store.loadDefaults(
        templates: templates.map((item) => item.toItem()).toList(),
        paperFormats: paperFormats.map((item) => item.toItem()).toList(),
        categories: categories.map((item) => item.toItem()).toList(),
      );
    }
    _apply(library);
    _loaded = true;
  } catch (error, stack) {
    debugPrint('Print library not loaded: $error\n$stack');
    _error = error;
  } finally {
    _loading = false;
    notifyListeners();
  }
}
