Web Locale Keymap

This package maps Web's KeyboardEvent to Flutter's logical keys. It only includes "locale sensitive" keys, which are all the letters, regular digits, and symbols. It works for all layouts shown in Microsoft/VSCode repo.

The mapping data and test cases are generated by gen_web_locale_keymap package. Do not edit them manually.

Usage

1. Ensure that the key is a locale key.
2. Get the logical key from getLogicalKey().
3. If the return value is null, then the key can not be mapped as a character either. Mint the logical key value.

import 'package:web_locale_keymap/web_locale_keymap.dart' as locale_keymap;

final locale_keymap.LocaleKeymap mapping =
    locale_keymap.LocaleKeymap.win(); // Or .darwin() or .linux()

/* ... */

int getLogicalKey(html.KeyboardEvent event) {
  int? result = _convertToDeadKey(event)
             ?? _convertToUnprintableKey(event)
             ?? _convertToNumpadKey(event);
  if (result != null) {
    return result;
  }
  result = mapping.getLogicalKey(event.code, event.key, event.keyCode);
  if (result != null) {
    return result;
  }
  return _mintLogicalKey(event);
}
