Recommended: JavaScript SDK with React Hooks

For new React apps, we recommend the JavaScript SDK with React Hooks (@dynamic-labs-sdk/react-hooks) instead of the legacy React SDK documented here. The JS SDK comes with many benefits such as a much smaller bundle size and other optimizations. Use the React quickstart (JavaScript SDK) to get started.

Summary

This callback will be called when the auth modal is closed before authentication is successful. Note that onAuthFlowClose will also still be called — if you want an event that is fired whenever the auth modal is closed, you should listen to it.

Usage

<DynamicContextProvider
  settings={{
    events: {
      onAuthFlowCancel: () => {
        console.log('Authentication was cancelled');
      }
    }
  }}
>
 {/* ... rest of your app ... */}
</DynamicContextProvider>
