How to convert from .NET to Dart

Transitioning from .NET to Dart can seem daunting at first, but with the right guidance, it can be a smooth and rewarding process. Dart, a programming language optimized for creating mobile, desktop, server, and web applications, offers a modern alternative to .NET. In this guide, we'll walk you through the steps to convert .NET code to Dart efficiently.

Understanding the Core Differences Between .NET and Dart

Language Syntax and Semantics

.NET primarily uses C#, a statically-typed language with rich syntax. Dart is also a statically-typed language but has a different syntax, more akin to languages like Java or JavaScript. Here are some key differences to keep in mind:

  • Method Definitions: In C#, methods are defined with keywords like public, private, etc. In Dart, visibility is managed using underscores (_) to denote private members.
  • Null Safety: Dart has built-in null safety, meaning you have to explicitly declare nullable types using a question mark (?).

.NET Namespaces vs. Dart Packages

.NET uses namespaces to organize classes, whereas Dart uses packages:

  • .NET Namespace Example:
    using System;
  • Dart Package Example:
    import 'dart:core';

While converting, you'll need to map .NET namespaces to their corresponding Dart packages.

Converting Data Types

Both .NET and Dart support primitive and complex data types, but they differ in their implementations:

  • Primitive Data Types:

    int number = 10;  // .NET
    int number = 10;  // Dart
  • String Handling:

    string text = "Hello, World!";  // .NET
    String text = 'Hello, World!';  // Dart

Object-Oriented Programming

Class Definitions and Constructors

In .NET, a class is typically defined with its members and constructors using explicit visibility:

  • .NET Class:
    public class Person
        public string Name { get; set; }
        public Person(string name)
            Name = name;

In Dart, classes are structured similarly but with some syntax changes:

  • Dart Class:
    class Person {
      String name;
      Person(this.name);  // Constructor shorthand

Converting Functions and Methods

Functions in Dart use a simpler syntax compared to .NET:

  • .NET Method:

    public int Add(int a, int b)
        return a + b;
  • Dart Function:

    int add(int a, int b) {
      return a + b;

Asynchronous Programming

Async and Await

Both .NET and Dart support asynchronous programming patterns, using async and await keywords. The conversion is quite straightforward:

  • .NET Asynchronous Method:

    public async Task<string> FetchDataAsync()
        var data = await SomeAsyncOperation();
        return data;
  • Dart Asynchronous Method:

    Future<String> fetchData() async {
      var data = await someAsyncOperation();
      return data;

Exception Handling

Exception handling is essential in any programming language. Both .NET and Dart use similar try-catch-finally constructs:

  • .NET Exception Handling:

        // Code that may throw an exception
    catch (Exception ex)
        // Handle exception
        // Code to execute regardless of an error
  • Dart Exception Handling:

    try {
      // Code that may throw an exception
    } catch (e) {
      // Handle exception
    } finally {
      // Code to execute regardless of an error

Wrapping Up

Converting from .NET to Dart involves understanding the core differences in language syntax, libraries, and idioms. By starting with the basic concepts and progressively tackling more complex structures, you can efficiently transition your codebase to Dart. This guide is aimed at providing a detailed roadmap to ensure a smooth conversion process. Whether you’re converting a small utility or a large application, these steps will help you adapt your .NET skills to the Dart ecosystem effortlessly.
