Using a function is almost the same as using what the function returns in place of that function. So, if you are calling a widget constructor and giving it as a child to another widget, you are not making your code inefficient by moving that constructor call into a function....
it's more efficient to build that subtree once/// instead of rebuilding it on every animation tick./// If the pre-built subtree is passed as the [child] parameter, the/// [AnimatedBuilder] will pass it back to the [builder] function so that it/// can be incorporated into the build...
Second, the state that you do manage yourself can be separated into two conceptual types: ephemeral state and app state. 从广义上来说,应用程序的状态是应用程序运行时内存中存在的所有内容。这包括应用程序的资源、Flutter 框架保持的有关 UI、动画状态、纹理、字体等的所有变量。虽然这种最广泛的状态定义...
异步交互可能需要一个理想的机会来进行总结。偶尔，在周期结束之前可能会发出一些值。在 Dart 中，您可以创建一个返回 Stream 的容量，该容量可以在异步进程处于活动状态时发射一些值。假设您需要根据一个 Stream 的快照在 Flutter 中构造一个小部件，那么有一个名为 StreamBuilder 的小部件。
And finally, let’s call that new function from our build method. Copy @override Widget build(BuildContext context) { _updateDualScreenInfo(); ... // The rest of the build method } That’s it! Now we have an application that will work on both a dual-screen and single-screen device....
