I have a function which loads data to TextFormField from firebase .
can we supply controller to the TextFormField created by following function.

 loadDataToTextFormField(
      QuerySnapshot mySnapshot,
      int index,
      String databaseField,
      String? bulletsAndNumberingType,
      TextStyle textStyle) {
    List getDataList = List.from(mySnapshot.docs[index][databaseField]);
    return Column(
      children: [
        for (var i in getDataList)
          Align(
            alignment: Alignment.centerLeft,
            child: TextFormField(
                //  controller: ?? how to supply controller here,
                initialValue:
                    "$bulletsAndNumberingType  $i", 
                style: (textStyle)
                ),
          ),
      ],
    );

    You can supply controller to the TextFormField by use following function.

    loadDataToTextFormField(
      QuerySnapshot mySnapshot,
      int index,
      String databaseField,
      String? bulletsAndNumberingType,
      TextStyle textStyle) {
    List getDataList = List.from(mySnapshot.docs[index][databaseField]);
    List<TextEditingController> textEditingControllerList =
        List<TextEditingController>.filled(
            getDataList.length, TextEditingController());

    return Column(
      children: [
        for (var i in getDataList)
          Align(
            alignment: Alignment.centerLeft,
            child: TextFormField(
                controller: textEditingControllerList[i],
                initialValue: "$bulletsAndNumberingType  $i",
                style: (textStyle)),
          ),
      ],
    );
  }
