Material Segmented Control

A material segmented control like the one for iOS, in Material style.

Why?

We all know well the Cupertino segmented widget in Flutter. But there is no similar in Material, so I thought, why not to create one.

You can check it out on pub.dev: (see package on pub.dev)

How to use

Import the package

In your pubspec.yaml, add

dependencies: 
    material_segmented_control: ^5.0.1

Import code

Wherever you want to use this widget, import

import 'package:material_segmented_control/material_segmented_control.dart';

Basic usage

int _currentSelection = 0;

MaterialSegmentedControl(
    children: _children,
    selectionIndex: _currentSelection,
    borderColor: Colors.grey,
    selectedColor: Colors.redAccent,
    unselectedColor: Colors.white,
    selectedTextStyle: TextStyle(color: Colors.white),
    unselectedTextStyle: TextStyle(color: Colors.redAccent),
    borderWidth: 0.7,
    borderRadius: 32.0,
    disabledChildren: [3],
    onSegmentTapped: (index) {
      setState(() {
        _currentSelection = index;
      });
    },
);

Map<int, Widget> _children = {
  0: Text('Hummingbird'),
  1: Text('Kiwi'),
  2: Text('Rio'),
  3: Text('Telluraves')
};

Features

• Disable the selection for all children by setting selectionIndex to null. It un-selects all options.
• Disable children to being not "clickable" (like setting onPressed to null on a button) by setting disabledChildren. Give it a list with all indices that should be disabled. Give it either null or an empty list to not use the disabled feature.
