Get Multiple Inputs from User – Flutter

I have a form with about 15 textform fields to input data by the user. What is the best solution for this?

I have currently created a list like below:

List<TextEditingController> textController = [
    TextEditingController(), //name
    TextEditingController(), //location
    TextEditingController(), //days
    TextEditingController(), //year
    TextEditingController(), //hour
    TextEditingController(), //minutes
    TextEditingController(), //seconds
    TextEditingController(), //lat_dec
    TextEditingController(), //lng_dec
    TextEditingController(), //lat_deg
    TextEditingController(), //lat_min
    TextEditingController(), //lat_sec
    TextEditingController(), //lng_deg
    TextEditingController(), //lng_min
    TextEditingController(), //lat_sec
  ];

Can I reuse the the same TextEditingController to avoid so many variables?
Any suggestions?

    using the same TextEditingController for more than TextField has unexpected behavior which is:

    The text you are typing in a specific field will be simultaneously written to other fields that are controlled with the same controller.

    so, try to handle it through creating a map of controllers or even generate a list with specific length of controllers.

    Here is a method to create a dynamic list of TextEditingController() for every item/title without having to manually create them:

    List<String> titles = ['name','location'];
List<TextEditingController> controllers = [];

for (int i = 0; i < titles.length; i++) {
      controllers.add(TextEditingController());
}
