Library for creating and customizing sliders

Widget customization variations

Here are some examples of the library's features:

https://raw.githubusercontent.com/chahohbily/slide_switcher/HEAD/.github/switchers_example.gif

First I suggest you get familiar with what container and sliders are in the library

https://raw.githubusercontent.com/chahohbily/slide_switcher/HEAD/.github/container_sliders.png

The library lets you change the style of containers and sliders using the fields in the table below

List and description of the functionality:

Fields	Description
children	Widgets that placed inside sliders / required
onSelect	The function takes an index variable that changes depending on the index of the current slider / required
containerHeight	Container height / required
containerWight	Container width / required
slidersColors	The color of each slider. A single color in the array will fill all sliders / white by default
slidersGradients	The gradient of each slider. A single gradient in the array will fill all sliders
containerBorder	Container border widget
slidersBorder	Slider border widget
containerBorderRadius	Container corner rounding radius
containerColor	Container fill color / grey by default
indents	Indents between the container and sliders (the same on all sides) / 0 by default
direction	Defining the direction of the slider swipe / horizontal by default
isAllContainerTap	A shadow cast by a box
containerBoxShadow	Ability to tap on the current slider and change its index to the opposite (available only for 2 children) / false by default
initialIndex	Initial index of the slider, which is rendering for the first time

Creating your own SlideSwitcher

SlideSwitcher is an ordinary widget. In order to create it you have to specify the obligatory parameters: "children" - texts, icons, pictures and any other widgets that will be stored in the sliders; "onSelect" - the function which will be executed during the change of the focused slider; "containerHeight" - container height; "containerWight" - container width. To customize the widget you should use the optional parameters from the table above.

Minimum functionality:

SlideSwitcher(
  children: [
    Text('First'),
    Text('Second'),
  ],
  onSelect: (index) {},
  containerHeight: 40,
  containerWight: 350,
),

To change the state of the screen it is recommended to create a variable storing the index of the current slider and call its setState in the "onSelect" function

int switcherIndex1 = 0;

Column(
  children: [
    SlideSwitcher(
      children: [
        Text('First'),
        Text('Second'),
      ],
      onSelect: (index) => setState(() => switcherIndex1 = index),
      containerHeight: 40,
      containerWight: 350,
    ),
    const SizedBox(height: 20),
    if (switcherIndex1 == 0) ...[
      Container(height: 100, width: 100, color: Colors.red,)
    ]
    else ...[
      Container(height: 100, width: 100, color: Colors.green,)
    ],
  ],
),

List of exceptions for cases that are not supported by the library:

List of exceptions
All widgets from the list of "children" do not fit into the given container size
The "isAllContainerTap" parameter can be "true" only when "children" length is 2

The first error from the table occurs when the smallest side of the container (determined by the direction of the swipe) multiplied by the length of the "children" by half is greater than the largest side of the container. Only occurs when the borders of the container are maximum rounded

NEW

Vertical Switchers.

https://raw.githubusercontent.com/chahohbily/slide_switcher/HEAD/.github/vertical_switchers.png

The direction parameter of this library is responsible for the direction of the switch's movement. Just add direction: Axis.vertical to your widget:

SlideSwitcher(
  children: [
    Text('First'),
    Text('Second'),
  ],
  onSelect: (index) {},
  containerHeight: 350,
  containerWight: 40,
  direction: Axis.vertical
),

Empty Switchers

https://raw.githubusercontent.com/chahohbily/slide_switcher/HEAD/.github/switch_on.png

If you need a switch with two children to determine whether to turn something on or off, then add empty containers to children parameters and parameter isAllContainerTap: true:

SlideSwitcher(
  children: [
    Container(),
    Container(),
  ],
  onSelect: (index) {},
  isAllContainerTap: true,
  containerHeight: 30,
  containerWight: 60,
),
