Flutter widget packages that can be used to input values in the form of currencies

money text form field

moneytextformfield is one of the flutter widget packages that can be used to input values in the form of currencies, by displaying the output format in realtime.

this widget is based on the fluttermoneyformatter package which has a very powerful ability to do currency formatting.

install

for complete steps in installing moneytextformfield you can see in the installation guide.

usage

the following is the simplest example of using moneytextformfield:

import 'package:moneytextformfield/moneytextformfield.dart';

  /// ... some lines of code ...
  moneytextformfield(
    settings: moneytextformfieldsettings()
  )
  /// ... some lines of code ...

for those who do not understand in implementing the code above, you can see the code below to create an application that can be directly used.

import 'package:flutter/material.dart';
import 'package:moneytextformfield/moneytextformfield.dart';

void main() => runapp(myapp());

class myapp extends statefulwidget {
  @override
  _myappstate createstate() => _myappstate();
}

class _myappstate extends state<myapp> {
  texteditingcontroller mycontroller = texteditingcontroller();

  @override
  void initstate() {  
    super.initstate();
  }

  @override
  widget build(buildcontext context) {
    return materialapp(
      home: scaffold(
        appbar: appbar(
          title: const text('moneytextformfield demo'),
        ),
        floatingactionbutton: floatingactionbutton(
          onpressed: () => print(mycontroller.text),
          child: icon(icons.save),
        ),
        body: column(
          children: <widget>[
            /// begin of :> moneytextformfield
            moneytextformfield(
              settings: moneytextformfieldsettings(
                controller: mycontroller
              )
            )
            /// end of :> moneytextformfield
          ]
        )
      )
    );
  }
}

from the above code it will look more or less like the following:

figure 1: using full format

by doing a little modification, you will get the following results:

figure 2: using compact format

referring to the example code above, to retrieve the value inputted by the user, you can get it through the mycontroller.text as in the onpressed event in the floatingactionbutton widget.

configurations

for now, moneytextformfield only uses one property to configure the display of that object, the settings property that has a data type is an instance of moneytextformfieldsettings.

moneytextformfieldsettings

tips:

no need to initialize the value in controller.text, because the value will be ignored. the controller property is only intended to capture the value inputted by the user.

notes:

the value contained in controller.text is exactly the same as the one inputted by the user and has a string data type. if you want to get results in the same format, you can use the fluttermoneyformatter package which is also used by moneytextformfield.
