Attach event listeners
The plugin uses event-based communication, and emits events when payment fails or succeeds.
The event names are exposed via the constants wlResponse from plugin class.
Use the on(String event, Function handler) method on the WeiplCheckoutFlutter instance to attach event listeners.

wlCheckoutFlutter.on(WeiplCheckoutFlutter.wlResponse, handleResponse);

The handlers would be defined somewhere as

void handleResponse(Map<dynamic, dynamic> response) {
// Do something when payment succeeds
}
