dart - 如何编写返回字符串的内联函数？

Question

假设我有一个返回字符串的愚蠢函数:

String oddMicrosecond() {
  if (DateTime.now().microsecondsSinceEpoch%2==0) {
    return "we're even";
  } else {
    return "that's odd";
  }
}

Text(oddMicrosecond());

是否可以将其编写为 Text 声明中的内联匿名函数而不单独定义它？

Answer 1

你不需要那个函数

Text(DateTime.now().microsecondsSinceEpoch%2==0 ? "that's odd" : "we're even")

你可以

Text(() {
    if (DateTime.now().microsecondsSinceEpoch%2==0) {
      return "we're even";
    } else {
      return "that's odd";
    }
  }();
)
