Dart Keywords

Keywords are the reserved words of a programming language, and they have a special meaning that comes defined by the language. These cannot be used as an identifier, and all these keywords are case-sensitive.

Whenever we use any keyword in our code, the lexical analysis phase of the compilation process returns a token associated with the keyword to a parser, which is then checked for validation.

There are 61 keywords in the Dart language. Here is the list of keywords offered by Dart:

1. Keywords with subscript 1 are conceptual keywords that have special meaning only in specific places. They are valid identifiers everywhere.

2. Keywords with subscript 2 are built-in identifiers. These keywords are valid identifiers almost everywhere, except they can’t be used as a class or type name, or as import prefixes.

3. Keywords with subscript 3 are limited reserved words related to asynchrony support.
