+Local Storage is a simple key/value storage interface
+for Strings. Use Dart's local storage interface as a
+Map.

+
+Note, local storage, though widely supported, is a
+synchronous API. Because it involves IO, this interface
+should not be used for high throughput operations.
+You might consider IndexedDB as an alternative.
+
+For simple string keys and values, and as a replacement
+for cookies, local storage is useful.
