SciDart is an experimental cross-platform scientific platform for Dart.

🏹 Goals

The main goal of SciDart is run the main module where Dart can run, in other words, run on Flutter, Dart CLI, Dart web, etc. Beside, offer tools to help the data analysis.

🏃 Motivation

Some time ago I tried make a guitar tuner (frequency estimator) with Flutter and, I faced with the problem: Dart didn't have a unified scientific library. So, I tried implement something to help me and the community with this problem.

📦 SciDart modules

The SciDart are the combination of the following modules:

• SciDart: main library with all the numerical processing routines. It can run everywhere (Github / PUB);
• SciDart IO: library to handle data files, for now, was made to run only in Desktop (Github / PUB);
• SciDart Plot: library to plot the data (Github / PUB);

🔌 Installation

Choose your package and following the instructions in the PUB website.

• Line plot (code):

  

• Stem plot (code):

  

• Pie plot (code):

  

• Plot export formats: SVG string that can saved or redered anywhere;

🖥 Dart REPL for prototyping quickly

Dart don't have REPL by default, but I found this amazing post from Andreas Kirsch and He implemented an experimental Dart REPL but the current library don't support Dart SDK > 2.0.0. So, I decided to leave this work pending for now.

🙌 How to contribute

I recommend check the Projects section and choose a task or choose and solve a problem with SciDart and implement the missing parts and read the file CONTRIBUTING.md.

The reference values for all functions came from with SciPy. The contributions need use SciPy as reference too.

Every contribution need to have tests, documentation and examples, otherwise, the pull request will be blocked.
