# Statistics

```dart
FlutterMapTileCaching.instance.rootDirectory.stats; // Roots
FlutterMapTileCaching.instance('storeName').stats; // Stores
```

## Watching For Changes

```dart
FMTC.instance.rootDirectory.stats.watchChanges(); // Roots
FMTC.instance('storeName').stats.watchChanges(); // Stores
```

It is possible to watch for changes in structures, which can be useful to create dynamic UIs (using `StreamBuilder`s) that consume the other statistics. There are lots of customization options to increase efficiency and reduce junk/useless rebuilds.
