charcode.ascii.dollar_lowercase library Null safety

Declare integer constants for each ASCII character.

The constants all start with "$" to avoid conflicting with other constants.

For characters that are valid in an identifier, the character itself follows the "$". For other characters, a symbolic name is used. In some cases, multiple alternative symbolic names are provided. Please stick to using one name per character in your code.

The symbolic names are, where applicable, the name of the symbol without any "mark", "symbol" "sign" or "accent" suffix. Examples: $exclamation, $pipe, $dollar and $grave. For less common symbols, a selection of common names are used.

For parenthetical markers, there is both a short name, $lparen/$rparen, and a long name, $open_paren/ $close_paren.

For common HTML entities, the entity names are also usable as symbolic names: $apos, $quot, $lt, $gt, and $amp.
