flutter - 如何同时循环两个列表 - Flutter

Question

我试图同时遍历两个列表

例如

List A = ['Chapter 1','Chapter 2','Chapter 3'];
List B = ['Paragraph 1','Paragraph 2','Paragraph 3'];

for(var chapter in A)  // This would itreate through only first list (A), How can I iterate through both list
children: [
     Text(chapter);   
     Text(paragraph);
]

我需要在“for”循环中同时遍历两个列表。

Answer 1

代码如下:

  List A = ['Chapter 1','Chapter 2','Chapter 3'];
  List B = ['Paragraph 1','Paragraph 2','Paragraph 3'];
  for (int i = 0; i < A.length; i++) {
      print ("${A[i]}");
      print ("${B[i]}");
  }

如果这没有帮助，请告诉我。
