flushSync

void flushSync(

  1. void callback()

)

Lets you force React to flush any updates inside the provided callback synchronously.

This ensures that the DOM is updated immediately. Use sparingly as it can hurt performance.

Example:

flushSync(() {
  state.set(newValue);
});
// DOM has been updated

Implementation

void flushSync(void Function() callback) {
  _reactDomFlushSync(callback.toJS);
}
