CurrencyInputFormatter class

A custom TextInputFormatter for formatting currency input dynamically.

This formatter takes raw numerical input and formats it as currency in real time. It supports locale-based formatting and a customizable currency symbol.

Parameters:

• locale: The locale to use for formatting (e.g., 'en_US', 'fr_FR').
• currencySymbol: The symbol to use for the currency (e.g., '$', '€').

Behavior:

• Removes all non-numeric characters from the input.
• Divides the number by 100 to represent a monetary value.
• Formats the resulting value as currency based on the locale and symbol.

Examples:

final formatter = CurrencyInputFormatter(locale: 'en_US', currencySymbol: '\$');// Input: "12345" // Output: "$123.45"

final frenchFormatter = CurrencyInputFormatter(locale: 'fr_FR', currencySymbol: '€');// Input: "12345" // Output: "123,45 €"
