When you think about mobile app then First step of app is Splash screen. So why we should not implement attractive UI with animation in Splash screen? Here we serve animated splash screen for Flutter.

You can Download Source Code via Github.

Splash Screen

It is very easy to implement Splash screen in flutter as following simple code

 animationController = new AnimationController(
        vsync: this, duration: new Duration(seconds: 4));
    animation =
        new CurvedAnimation(parent: animationController, curve: Curves.easeOut);

    animation.addListener(() => this.setState(() {}));
    animationController.forward();

    setState(() {
      _visible = !_visible;
    });
    startTime();

startTime() async {
    var _duration = new Duration(seconds: 3);
    return new Timer(_duration, navigationPage);
  }

  void navigationPage() {
    Navigator.of(context).pushReplacementNamed(HOME_SCREEN);
  }

Intro Screen

Here I have attached Intro screen code as following

FadeAnimation(
                        2,
                        Text(
                          page.toString(),
                          style: TextStyle(
                              color: Colors.white,
                              fontSize: 30,
                              fontWeight: FontWeight.bold),
                        )),

Expanded(
                  child: Column(
                    mainAxisAlignment: MainAxisAlignment.end,
                    crossAxisAlignment: CrossAxisAlignment.start,
                    children: <Widget>[
                      FadeAnimation(
                          1,
                          Text(
                            title,
                            style: TextStyle(
                                color: Colors.white,
                                fontSize: 50,
                                height: 1.2,
                                fontWeight: FontWeight.bold),
                          )),
                      SizedBox(
                        height: 20,
                      ),
                      FadeAnimation(
                          2,
                          Padding(
                            padding: const EdgeInsets.only(right: 10),
                            child: Text(
                              description,
                              style: TextStyle(
                                  color: Colors.white.withOpacity(.7),
                                  height: 1.9,
                                  fontSize: 15),
                            ),
                          )),
                      SizedBox(
                        height: 20,
                      ),
                      FadeAnimation(
                          2.5,
                          Text(
                            'READ MORE',
                            style: TextStyle(color: Colors.white),
                          )),
                      SizedBox(
                        height: 30,
                      ),
                    ],
                  ),
                )

Here I have attached Login animation code as following

Icon Animation

AvatarGlow(
                  endRadius: 90,
                  duration: Duration(seconds: 2),
                  glowColor: Colors.white24,
                  repeat: true,
                  repeatPauseDuration: Duration(seconds: 2),
                  startDelay: Duration(seconds: 1),
                  child: Material(
                      elevation: 8.0,
                      shape: CircleBorder(),
                      child: CircleAvatar(
                        backgroundColor: Colors.grey[100],
                        child: FlutterLogo(
                          size: 50.0,
                        ),
                        radius: 50.0,
                      )),
                )

Text Animation

 DelayedAnimation(
                  child: Text(
                    "Hi There",
                    style: TextStyle(
                        fontWeight: FontWeight.bold,
                        fontSize: 35.0,
                        color: color),
                  ),
                  delay: delayedAmount + 1000,
                ),

add following lib code in your .yaml file
