                padding: const EdgeInsets.only(left: 20.0, right: 20.0),
                child: new Row(
                  children: <Widget>[
                    new Expanded(
                      child: FlatButton(
                        shape: new RoundedRectangleBorder(
                            borderRadius: new BorderRadius.circular(30.0)),
                        splashColor: this.primaryColor,
                        color: this.primaryColor,
                        child: new Row(

                              ),
                            ),
                            new Expanded(
                              child: Container(),
                            ),
                            new Transform.translate(
                              offset: Offset(15.0, 0.0),
                              child: new Container(
                                padding: const EdgeInsets.all(5.0),
                                child: FlatButton(
                                  shape: new RoundedRectangleBorder(
                                      borderRadius:
                                          new BorderRadius.circular(28.0)),
                                  splashColor: Colors.white,
                                  color: Colors.white,
                                  child: Icon(
                                    Icons.arrow_forward,
                                    color: this.primaryColor,
                                  ),
                                  onPressed: () {
                                    box.write('lang', 'en_US');
                                    Get.to(() => LoginScreen1());
                                  },
                                ),
                              ),
                            )
                          ],
                        ),
                        onPressed: () {
                          box.write('lang', 'en_US');
                          Get.to(() => LoginScreen1());
                        },
                      ),
                    ),
                  ],
                ),
              ),

the second page

Padding(
                  padding: const EdgeInsets.only(left: 40.0),
                  child: Text(
                    'serverAddress'.tr,
                    style: TextStyle(color: Colors.grey, fontSize: 16.0),
                  ),
                ),

There is more than this too

Answer 1

In the onPressed function, we can use the Get.updateLocale function accordingly:

onPressed: () {
  box.write('lang', 'en_US');
  Locale locale = Locale('en','en_US');
  Get.updateLocale(locale);
  Get.to(() => LoginScreen1());
}
