Flipper​
For projects that use Flipper, there is a Flipper plugin called Advanced Async Storage. The plugin provides basic CRUD operations on Async Storage.
Non Flipper​
For the projects which aren't using Flipper, you can use the React Native Debugger which comes with a built-in Async Storage support. The debugger allows to print the Async Storage content to the console, and clear it completely.
