Zapp!

Zapp! is a free online Dart & Flutter sandbox that lets you run Dart code in the browser. It's great for sharing code snippets in your documentation.

Embedding Zapp!

Use the <Zapp> component and pass the ID of the Zapp! you want to embed.

<Zapp id="flutter" />

Lazy Loading

To prevent the sandbox from loading until the user interacts, pass the lazy prop.

<Zapp lazy id="flutter" />
