在flutter中设置TextEditingController数组的最佳方法是什么.我的意思是我需要获取一个Textfield(1到n)值的值数组并将其发送到服务器.

What is the best way to set an array of TextEditingController in a flutter . I mean I need to get a value array of Textfield(1 to n) value and sent to the server.

任何人都可以帮助实现这一目标吗?

Can anyone help how to achieve this?

我尝试了

TextEditingController _controller[i] = TextEditingController(); 
}

推荐答案

有很多方法可以做到这一点

There are plenty of ways to do that

List<TextEditingController> _controller = List.generate(74, (i) => TextEditingController());

或

List<TextEditingController> _controller = [];
for (int i = 1; i < 75; i++) _controller.add(TextEditingController());

或

List<TextEditingController> _controller = [
  for (int i = 1; i < 75; i++)
    TextEditingController()
];
