Get double value, get int value and get number in string format #
To get the number value from controller, you can use both the doubleValue or the intValue properties:
//Double value:
final double val = controller.doubleValue;
copied to clipboard
//Int value:
final int val = controller.intValue;
copied to clipboard
//String number:
final int val = controller.textWithoutCurrencySymbol;
copied to clipboard
Initial value #
You can initialize the controller using a int or a double, but not both at the same time.
To make this, just use initDoubleValue or initIntValue:
final CurrencyTextFieldController controller2 = CurrencyTextFieldController(initDoubleValue: 10);
final CurrencyTextFieldController controller3 = CurrencyTextFieldController(initIntValue: 1000);

// this will raise an error!
final CurrencyTextFieldController controller4 = CurrencyTextFieldController(initIntValue: 1000,initDoubleValue: 10);

Position of the symbol and separator #
You can decide if the symbol will be before or after the number.
To make this, just use currencyOnLeft:
// default with the currency before the number
final CurrencyTextFieldController controller = CurrencyTextFieldController();

// currency after the number
final CurrencyTextFieldController controller2 = CurrencyTextFieldController(currencyOnLeft: false);
copied to clipboard
And also define the separator between the symbol and the value with currencySeparator:
// the default value is a single space
final CurrencyTextFieldController controller = CurrencyTextFieldController(currencySeparator: ' -> ');
copied to clipboard
Block the user from setting negative numbers #
Just set enableNegative to false
Force a value from outside the TextField #
final CurrencyTextFieldController controller = CurrencyTextFieldController();
// using a double
controller.forceValue(initDoubleValue: 300.5);

// using an int
controller.forceValue(initIntValue: 10000);
copied to clipboard
Change the currency symbol of the controller #
final CurrencyTextFieldController controller = CurrencyTextFieldController();
// keeping the current value:
controller.replaceCurrencySymbol('EUR');

// reseting the current value:
controller.replaceCurrencySymbol('EUR', resetValue: true);
