Flutter - Performance best practices

Minimize expensive operations 몇몇 연산자들은 다른 연산자들보다 더 많은 리소스를 소모합니다. 앱의 UI를 어떻게 디자인하고 구현하는지가 얼마나 효율적으로 앱이 작동하는지 큰 영향을 줍니다. Control build() cost UI를 디자인 할 때 항상 생각해야할 것이 있습니다. 상위 위젯을 rebuild 할 때 해당 위젯의 build()가 자주 호출될 수 있으므로, build() 메소드에서 반복적이고 비용이 많이 드는 작업을 피하세요. 큰 build() 함수가 있는 지나치게 큰 단일 위젯을 만드는 것을 피하세요. 캡슐화뿐만 아니라 위젯들이 어떻게 변하는지에 따라 위젯을 다른 위젯들로 분할하세요.
