matrix_input

A package that leverages on the power of flutter widgets to display data in matrix form.

Getting Started

Instead of hard coding the widgets to represent matrices, let this package make life bearable for you!

Features

Use this package in your flutter app to:

  • Place data i.e. numbers in matrix form.
  • Perform arithmetic operations.
  • Build puzzles which requires numbers displayed in matrix form.
  • Teach i.e. perfect squares.

Setup

Import it in your project:

import 'package:matrix_input/matrix_input.dart';

Most importantly, bundle it in either a row or column.

Note: the "matrixController" is required. Just like a normal TextEditingController.

Thus, declare your TextEditingController textEditingController; i.e TextEditingController r0c0; Implying Row1Column0 e.t.c

Make sure to initialize it in the init() section. Refer to example folder.

Usage Examples

  • 1x3 Matrix

  • Sample code
class _MatrixState extends State<Matrix> {

  //Create text controllers
  final r0c0 = TextEditingController(text: '8');
  final r0c1 = TextEditingController(text: '9');
  final r0c2 = TextEditingController(text: '10');

  @override
  void initState() {
    super.initState();
  }

  @override
  void dispose() {
    //Clean up the controller when the widget is removed from the
    // widget tree.
    r0c0.dispose();
    r0c1.dispose();
    r0c2.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('matrix_input'),
      ),
