📄Need a local document?

Flutter Matrix provides a local doc (by markdown, but you need to rename the folder to docs first) folder and a mkdocs-based building module. If you have Python in your environment, change to the same directory as the mkdocs.yml file and run the following command.

pip install mkdocs mkdocs-material pymdown-extensions mkdocs-material-extensions

After successfully installing the above libraries, run the following command again. You will find that you have generated a folder named site. Open the index.html in the folder to browse the online web documents.

mkdocs build

🛎️Attention.

• Flutter Matrix can run in a pure Dart environment.

✍️Example

• Use arrange to generate a data matrix with evenly spaced intervals.

import 'package:flutter_matrix/matrix_type.dart';

main(){
  data_format = "%2.0f";
  var t = MatrixBase.linspace<Matrix>(
      row: 10, 
      column: 10, 
      start: 1, 
      end: 100, 
      keep: true
  );
  t.visible();
}

• Output.
