flutter - 将字符串拆分为 Dart 中的关键字

Question

如果我有一个字符串，上面写着“This is a good example”，有什么方法可以将它拆分为 dart 中的以下输出:

This
This is
This is a
This is a good
This is a good example

Answer 1

我会这样做:

String text = "This is a good example";
List<String> split = text.split(" ");
for (var i = 0; i < split.length; i++) {
  print(split.sublist(0, i + 1).join(" "));
}
