# Software architecture of interpreter in Dart (Flutter)

This project is a part of my tech talk about OOP design of interpreters. 

## Arithmetic expressions interpreter. 
The software accept arithmetic expression in input and provide 3 interpretation: 
* Result of evaluation
* Abstract Syntax Tree structure
* Stack machine assembler representation

### Demo Application 
  * The web app is available here ->  [demo](https://euler2dot7.github.io/interpreter/#/)

### Example:
