• 변수 설정

homepage.dart

static double birdY = 0;
double initialPos = birdY;
double height = 0;
double time = 0;
double gravity = -4.9; // how strong the gravity is
double velocity = 3.5; // how strong the jump is
double birdWidth = 0.1; // out of 2, 2 being the entire width of the screen
double birdHeight = 0.1; /

• 방벽 구현

  barrier.dart

  class MyBarrier extends StatelessWidget {
  final size;
  
  MyBarrier({this.size});
  
  @override
  Widget build(BuildContext context) {
  return Container(
      width: 100,
      height: size,
      decoration: BoxDecoration(
        color: Colors.green,
        border: Border.all(width: 10, color: Colors.greenAccent),
        borderRadius: BorderRadius.circular(15)
      ));

}

• 내용 정리

중력과 가속도를 설정해주어 새가 정교하게 움직일 수 있게하고, Y축으로 움직이는새가 -1,1에 만났을 경우 게임이 종료된다. 방벽은 4개로 구현하고, X축을 barrierXone으로 설정해주어 방벽이 움직이게 한다.
