30秒学会 Dart 片段 – fibonacci

Generates a list, containing the Fibonacci sequence, up until the nth term.

Use List.generate() to generate a list with n terms, using a function that returns the sum of the last two values, except for the first two.

代码实现

List<int> fibonacci(int n) {
  int last = 1;
  int last2 = 0;
  return List<int>.generate(n, (int i) {
    if (i < 2) return i;
    int curr = last + last2;
    last2 = last;
    last = curr;
    return curr;
  });
}

使用样例

fibonacci(6); // [0, 1, 1, 2, 3, 5]
