List<TextEditingController>? remark = [];
List<TextEditingController>? remarkMask = [];

TextFormField(
    controller: notes![index],
    onChanged: (value) {
      if (notes1Mask![index] != value) {
        isButtonEnable = true;
      } else {
        isButtonEnable = false;
      }
    },
    decoration: InputDecoration(
      border: InputBorder.none,
      contentPadding:
          const EdgeInsets.all(10.0),
      fillColor: Colors.white,
      filled: true,

My question, How to get value from TextEditingController in ListView?

I tried print(notes), I got this result:

[TextEditingController#d4602(TextEditingValue(text: ┤Persiapan Sholat Shubuh 2 rokaats├, selection: TextSelection.collapsed(offset: 33, affinity: TextAffinity.downstream, isDirectional: false), composing: TextRange(start: -1, end: -1))),

As the result, you are getting is list of TextEditingController because List<TextEditingController>? notes = [];. To get text from it, you can do looping,

if (notes == null) return;
    for (final noteController in notes!) {
      print(noteController.text);
    }

To get notes text as List, you can use

List<String>? notesText =
     notes?.map((controller) => controller.text).toList();
