patchNumberSeperators static method

Future<void> patchNumberSeperators({ bool patchForSamsungKeyboards = false, })

patchNumberSeperators patches all locales with the decimal seperators to the decimal separator of the user. The locales can also be patched for users with a samsung keyboard. This is done by changing the patchForSamsungKeyboards to true. The samsung keyboard always uses a '.' as input for a decimal seperator. This means that the DECIMAL_SEP is a '.' and the GROUP_SEP is a ',' see https://github.com/flutter/flutter/issues/61175

Implementation

static Future<void> patchNumberSeperators({
  bool patchForSamsungKeyboards = false,

  final localePlus = LocalePlus();

    final String? userDecimalSeperator =
        isUsingSamsungKeyboard ? '.' : await localePlus.getDecimalSeparator();

    final String? userGroupingSeperator = isUsingSamsungKeyboard
        ? ','
        : await localePlus.getGroupingSeparator();

    if (userDecimalSeperator == null || userGroupingSeperator == null) {
      return debugPrint('''
