flutter format currency in texformfield-CodePudding

I have a flutter app which accepts an amount of money as input using a textformfield. I would like to format the input in textformfield so that whatever is being input can be formatted as currency copmlete wiht thousand separator commas. I have tried using the intl package number formatter but all I can do is print it to the command line.

Here is how it looks currently

This is how I would like it to look like

This is the textfield code

  TextEditingController currencyControler = TextEditingController();

  String? amount;

 TextFormField(
              controller: currencyControler,
              keyboardType: TextInputType.number,
              validator: (value) {
                if (value!.isEmpty) {
                  return 'Please enter an amount';
                }
                return null;
              },
              onSaved: (String? value) {
                amount = value;
              },
              decoration: InputDecoration(
                icon: const Icon(Icons.money_outlined),
                labelText: "Amount",
                hintText: 'Enter an amount',
                border: OutlineInputBorder(
                  borderRadius: BorderRadius.circular(8.0),
                ),
              ),
            )

How can I format the input so that the comma separators appear as any number is being entered
