What is the best way to define/store when I have a lot of TextFormField widgets in Flutter?

Question

I have 20 input fields in my app. What is the best way to define TextFormField widgets?

For example:

Column(
          children: [
            _buildCariUnvanTextField(unvanController),
            _buildCariUnvanTextField(unvanController),
            _buildCariUnvanTextField(unvanController),
            _buildCariUnvanTextField(unvanController),
            _buildCariUnvanTextField(unvanController),
            _buildCariUnvanTextField(unvanController),
            _buildCariUnvanTextField(unvanController),
            _buildCariUnvanTextField(unvanController),
            _buildCariUnvanTextField(unvanController),
            _buildCariUnvanTextField(unvanController),
          ],
        ),

Should I have 20 separate methods? Is it the correct way to define? Or what should I do? Can anyone explain?

You shouldn't have 20 different methods. You should use ListView.builder code like this:

ListView.builder(
  itemCount: 20,
  itemBuilder: (context, index) {
    return _buildCariUnvanTextField(unvanController);
  },
),

If the widgets are different, I think the only way is to have 20 different methods.

It's totally my fault that you don't understand the question. Each TextFormField is representing another field. I've duplicated the same widget just as an example. – Alican Kesen Oct 28 '22 at 10:15

I think too. I just wondered is there another way. Thank you – Alican Kesen Oct 28 '22 at 11:17

Avoid using helper methods altogether and instead define and use own defined classes/widgets.

What is the difference between functions and classes to create reusable widgets?
