Change codrova plugin Splash Screen anitmation

Hi I have a question how can I cahnge the cordova plugin for Splashscreen animation. Now it only can be hide,

 public boolean execute(String action, JSONArray args, CallbackContext callbackContext) {
    if (action.equals("hide")) {
        this.webView.postMessage("splashscreen", "hide");
    } else if (action.equals("show")){
        this.webView.postMessage("splashscreen", "show");
    }
    else {
        return false;
    }

how can i change instead hide to be animated in fadeout().
