Mate class

Mate is main class of library.

It has already created, Lexer and Expression. And two functions, calculate and isInvalidExp.

calculate is the main function that takes string expression, parses it (converts to tokens) by Lexer, and then by using Expression, calculates final result.

calculate function automatically checks given string expression's validness. if it's invalid, then function will return null, otherwise as normal a double number value.

Constructors

Mate({bool debugMode = false})

Properties

debugMode → bool
Decides running mode of mate. As default it's false, (adapted to release mode).
final
expression → Expression
Early created main expression. Used to store parts(tokens) and then calculate final result.
final
hashCode → int
The hash code for this object.
no setterinherited
lexer → Lexer

final
runtimeType → Type
A representation of the runtime type of the object.

Looks and returns if provided expression is invalid or not. (for our library)
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
