on method

ElementBuilder on(String event, EventCallback handler)

Generic event handler for custom or less common events.

Use specific handlers (onClick, onInput, etc.) when available. Use this for events not covered by the standard handlers.

Example:

Div().on('customevent', handleCustom)

Implementation

ElementBuilder on(String event, EventCallback handler) {
  // Normalize event name to camelCase with 'on' prefix
  final eventName = event.startsWith('on')
      ? event
      : 'on${event[0].toUpperCase()}${event.substring(1)}';

  _attrs[eventName] = EventAttribute.fromContext(handler);
  return this;
}
