Any Language Number Input Formatter Package

This package is designed to allow Flutter applications to utilize a custom input formatter for transforming different numeral systems into Arabic numerals. Specifically, it offers an AnyLanguageNumberInputFormatter that takes in numerals from various languages and outputs their Arabic numeral equivalents.

any.language.formater.MP4

📁 Package Structure

The main components of this package include:

AnyLanguageNumberInputFormatter: This custom TextInputFormatter implementation handles text input, formatting it by converting numerals from various languages into their Arabic numeral equivalents.

MyApp: The root widget of the example application. It sets up a MaterialApp widget.

MyHomePage: The home page of the example application, demonstrating the usage of TextField and TextFormField with the AnyLanguageNumberInputFormatter.

⚙️ How It Works

The AnyLanguageNumberInputFormatter class overrides the formatEditUpdate method. This method is called whenever a user alters the text in a text field. The formatter checks if the new value contains numerals in other languages and, if so, replaces them with their Arabic numeral equivalents.

The MyHomePage class contains a _disable flag. If this flag is true, the text fields don't use any input formatter. If it's false, they use the AnyLanguageNumberInputFormatter. Users can toggle the _disable flag by pressing a button.
