+# Dart solution by Eagerestwolf

+![Category](https://img.shields.io/badge/Category-faithful-green)
+
+This implementation of the Prime Sieve uses the Dart Programming Language,
+created by Google. The source file `bin/PrimeDart.dart` contains a lot of
+comments to allow someone not familiar with Dart to understand what the code is
+doing and why some things look a bit different to many other object oriented
+programming languages (i.e. Java, C#, C++, etc). The reason such thorough
+documentation is included is simple, Dave himself uses this algorithm when
+learning a new language, so I think this is a good opportunity to teach others
+a bit about Dart. So feel free to open that source file and take a read for
+yourself!
+
+## Run instructions
+
+**NOTE**: Owners of an Apple Silicon Mac *must* use the Dart SDK method. The
+Docker method will not work because Google does not publish arm64 images for
+Dart, and QEMU does not like running x64 images on arm64. Not an issue with my
+code, it's a known issue with Docker/QEMU/Dart's Docker images.
+
+To run this solution, you must either have [Docker](https://www.docker.com) or
+the [Dart SDK](https://dart.dev) installed.
+
+To run the solution using Docker, run the following command:
+
+```
+docker build -t primes-dart .
+docker run --rm -it primes-dart
+```
+
+To run the solution using the DartSDK, run the following command:
+
+```
+dart run
+```
+
+### Building and running
+
+Dart supports compiling a native binary for your operating system and 
+architecture. This is only supported using the Dart SDK, but can lead to 
+increased speed. To compile the binary, run the following command:
+
+```
+dart compile exe bin/PrimeDart.dart
+```
+
+Then run the binary with the following command:
+
+```
+bin/PrimeDart.exe
+```
+
+**NOTE**: The executable will always have a `.exe` extension, regardless of
+platform, but Dart will generate a standard ELF binary on *nix systems.
+
+## Output
