Install

Follow this guide

Usage

Import the library

import 'package:currency_textfield/currency_textfield.dart';

Create the Controller

CurrencyTextFieldController controller = CurrencyTextFieldController()

Parameters and getters

Currency Symbol, Decimal and Thousand separator

It's possible to customize leftSymbol, decimalSymbol and thousandSymbol:

var controller = CurrencyTextFieldController(leftSymbol: "RR", decimalSymbol: ".", thousandSymbol: ",");

Get double value and get int value

To get the number value from controller, you can use both the doubleValue or the intValue properties:

//Double value:
final double val = controller.doubleValue;

//Int value:
final int val = controller.intValue;

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);
