C# - Pass async Callback to Timer constructor, timer = new Timer (HandleTimerCallback, state, CommonConstants.InfiniteTimespan, CommonConstants.InfiniteTimespan); It really doesn't make sense to do this mixing of Timer and async/await. If you want timer behaviour in async/await world, just ...

这个批处理的需求,就可以使用Timer来实现,代码如下。 import 'dart:async'; import 'package:flutter/services.dart'; final BatchMethodChannel batchChannel = BatchMethodChannel(); class BatchMethodChannel { static const MethodChannel channel = MethodChannel('xys_flutter_batch_channel'); Timer? _timer; final...
上面的例子中,我们调用了someAsyncOperation,这个函数首先回去执行readFile方法,假设这个方法耗时95ms。接着执行readFile的callback函数,这个callback会执行10ms。最后才回去执行setTimeout中的callback。 所以上面的例子中,虽然setTimeout指定要在100ms之后运行,但是实际上还要等待95 + 10 = 105 ms之后才会真正的执行。
