#For Loop with Index This is a fundamental for loop, commonly found in most programming languages. It initializes the index to0and iterates through each element until the conditionlist.lengthis met. Example: voidmain() {List<String> words=["one","two","three"];print(words);for(inti=0;...
print('Do-while loop completed');}3. Future.forEach:用途: Future.forEach 用于遍历一组元素,并为每个元素执行异步操作。方法签名:dartCopy codestatic Future<void> forEach<T>(Iterable<T> elements, FutureOr<void> Function(T element) action)示例:dartCopy codeFuture<void> processItem(String item) ...
Also, there should not be any other statement in between a label name and an associated loop.Example: Label with BreakLive Demo void main() { outerloop: // This is the label name for (var i = 0; i < 5; i++) { print("Innerloop: ${i}"); innerloop: for (var j = 0; j <...
通常,break语句将从最近的封闭循环(无论是while,do还是for)或switch语句中逃脱。如果写入未包含在loop或switch中的break语句,则会发生编译时错误。 continue语句与break非常相似,但仅限于循环。它的作用不是逃避循环,而是立即继续下一次迭代。 6.3 SUMMARY Dart提供了相当传统的表达式和语句。主要目标是让主流程序员熟悉。

We can loop over the elements of a list withforEach,for, orwhileloops. main.dart import 'dart:io'; void main() { var vals = <int>[1, 2, 3, 4, 5]; vals.forEach((e) { stdout.write("$e "); }); print(""); for (var e in vals) { ...
