currency_input_formatter

A custom Flutter TextInputFormatter for currency values.

Usage

Initialize it in the inputFormatters parameter of a TextField or TextFormField.

Currently, there are two parameters:

allowSubdivisions - Whether or not to allow non-whole number values.
subdivisionMarker - The string separator in between the whole number and subdivision parts of a currency value.

Short Example

new TextField(
    autofocus: true,
    keyboardType: TextInputType.number,
    decoration: const InputDecoration(
        labelText: "Salary",
        prefixText: '\$',
    ),
    inputFormatters: <TextInputFormatter>[
      new CurrencyInputFormatter(
          allowSubdivisions: true,
          subdivisionMarker: "."
      ),
    ],
),
