Problem with entering money value from user with Flutter

Question

I get user double value with "Flutter Dart" language. But naturally, when I get a double value, it can only do dot (.) marking. Can I have it enter both period (.) and comma (,) markings at the same time without getting an error? Is something like this possible? Example: 1.750.50

try {
  if (aciklamaController.text.trim().length > 0) {
    SigortaKasko _kaydedilecekSigortaKasko = SigortaKasko(
      kim: _currentUser.userID,
      aciklama: aciklamaController.text,
      fiyat: double.parse(fiyatController.text.replaceAll(",", ".")).abs()

keyboardType: TextInputType.numberWithOptions(
                signed: true, decimal: true),
            controller: fiyatController,
            decoration: InputDecoration(
                hintText: "Fiyat Tutarını Giriniz",
                labelText: "Fiyat",
                border: OutlineInputBorder(
                    borderRadius: BorderRadius.circular(16))),
          )),
