Deprecated

at_sync_ui_flutter is deprecated. Version 1.2.0 is the final minor release and exists to keep existing apps compiling while they migrate away from foreground sync progress UI.

New Flutter apps should use AtCollection<T> and Query.watch() from at_client. Collections are backed by the local synced store by default, and their streams re-emit when local or remote updates arrive. In most screens, the UI should listen to collection streams directly instead of showing a global "sync in progress" indicator.

Migration

Use collection streams as the app-facing state source:

StreamBuilder<List<CItem<Todo>>>(
  stream: todos.query().where((todo) => !todo.obj.done).watch(),
  builder: (context, snapshot) {
    if (snapshot.hasError) {
      return ErrorView(error: snapshot.error!);
    }
    if (!snapshot.hasData) {
      return const Center(child: CircularProgressIndicator());
    }

    final items = snapshot.data!;
    if (items.isEmpty) {
      return const EmptyTodosView();
    }

    return TodoList(items: items);
  },
)

• Flutter reference app: packages/at_client_flutter/examples/todos

Legacy API

The existing AtSyncUIService, Material widgets, and Cupertino widgets remain available in this release for compatibility, but they are deprecated and should not be used in new code.
