(Flutter Slider) A material design slider and range slider, horizontal and vertical, with rtl support and lots of options and customizations for flutter
!! **Since version 3.4.0-dev.3, step type is no longer `double`, its `FlutterSliderStep`** !!
## Get Started
### Single Slider
A single slider
```dart
FlutterSlider(
values: [300],
max: 500,
min: 0,
onDragging: (handlerIndex, lowerValue, upperValue) {
_lowerValue = lowerValue;
_upperValue = upperValue;
setState(() {});
},
)
```
To make slider `Right To Left` use `rtl: true`
```dart
FlutterSlider(
...
rtl: true,
...
)
```
### Range Slider
A simple example of range slider
```dart
FlutterSlider(
values: [30, 420],
rangeSlider: true,
max: 500,
min: 0,
onDragging: (handlerIndex, lowerValue, upperValue) {
_lowerValue = lowerValue;
_upperValue = upperValue;
setState(() {});
},
)
```
### Vertical Axis
You can change the axis of your slider by setting `axis` to `Axis.vertical`. Default is horizontal
```dart
FlutterSlider(
...
axis: Axis.vertical,
...
)
```
 
## Handlers
You can customize handlers using `handler` and `rightHandler` properties.
Both `handler` and `rightHandler` accept `FlutterSliderHandler` class which has following properties:
1. `child`: is a widget
2. `disabled`: to disable the handler
3. `decoration`, `foregroundDecoration` and `transform` are come from `Container()` widget
```dart
FlutterSlider(
...
handler: FlutterSliderHandler(
decoration: BoxDecoration(),
child: Material(
type: MaterialType.canvas,
color: Colors.orange,
elevation: 3,
child: Container(
padding: EdgeInsets.all(5),
child: Icon(Icons.adjust, size: 25,)),
),
),
rightHandler: FlutterSliderHandler(
child: Icon(Icons.chevron_left, color: Colors.red, size: 24,),
),
...
)
```
### Handler Scale Animation
You can control the scale animation type of your handlers, it's duration and it's scale size using `handlerAnimation`
`handlerAnimation` accepts a `FlutterSliderHandlerAnimation` class which has 4 properties as following
```dart
FlutterSlider(
...
handlerAnimation: FlutterSliderHandlerAnimation(
curve: Curves.elasticOut,
reverseCurve: Curves.bounceIn,
duration: Duration(milliseconds: 500),
scale: 1.5
),
...
)
```
**if you don't want scale animation, then just pass `1` to `scale` property**
**if you don't want `reverseCurve`, just ignore it. default is null**
## Trackbars
To customize track bars you can use `FlutterSliderTrackBar`. [You can see the details here](https://pub.dartlang.org/documentation/flutter_xlider/latest/flutter_xlider/FlutterSliderTrackBar/FlutterSliderTrackBar.html)
```dart
FlutterSlider(
...
trackBar: FlutterSliderTrackBar(
activeTrackBarHeight: 5,
),
...
)
```
`inactiveTrackBarColor` and `activeTrackBarColor` properties are removed. use `inactiveTrackBar` and `activeTrackBar` instead.
```dart
FlutterSlider(
...
trackBar: FlutterSliderTrackBar(
inactiveTrackBar: BoxDecoration(
borderRadius: BorderRadius.circular(20),
color: Colors.black12,
border: Border.all(width: 3, color: Colors.blue),
),
activeTrackBar: BoxDecoration(
borderRadius: BorderRadius.circular(4),
color: Colors.blue.withOpacity(0.5)
),
),
...
)
```
### Central Widget
If you want to have a widget in the middle of your slider, you can use `centralWidget`
```dart
FlutterSlider(
...
trackBar: FlutterSliderTrackBar(
centralWidget: Container(
decoration: BoxDecoration(
color: trackBarColor,
borderRadius: BorderRadius.circular(50)
),
width: 9,
height: 9,
),
),
...
)
```
## Tooltips
In order to customize your tooltips, you can use `FlutterSliderTooltip` class. [You can see all properties here](https://pub.dartlang.org/documentation/flutter_xlider/latest/flutter_xlider/FlutterSliderTooltip/FlutterSliderTooltip.html)
```dart
FlutterSlider(
...
tooltip: FlutterSliderTooltip(
textStyle: TextStyle(fontSize: 17, color: Colors.white),
boxStyle: FlutterSliderTooltipBox(
decoration: BoxDecoration(
color: Colors.redAccent.withOpacity(0.7)
)
)
),
...
)
```
Here there is a range slider with customized handlers, trackbars and tooltips
### Tooltip Prefix
You can use `leftPrefix`, `leftSuffix`, `rightPrefix`, `rightSuffix` to add your desired widget around tooltip content.
```dart
FlutterSlider(
...
tooltip: FlutterSliderTooltip(
leftPrefix: Icon(Icons.attach_money, size: 19, color: Colors.black45,),
rightSuffix: Icon(Icons.attach_money, size: 19, color: Colors.black45,),
),
...
)
```
### Tooltip Format
If you want to change the format of the value of tooltip you can use `format` method.
```dart
FlutterSlider(
...
tooltip: FlutterSliderTooltip(
format: (String value) {
return value + ' ! ';
}
),
...
)
```
### Tooltip Callback
If you want to fully change tooltip widget and use your own customized widget, you can use `custom` function.
```dart
FlutterSlider(
...
tooltip: FlutterSliderTooltip(
custom: (value) {
return Text(value.toString());
}
),
...
)
```
### Disable Tooltip
To disable tooltips, use `disabled` in `FlutterSliderTooltip` class
```dart
FlutterSlider(
...
tooltip: FlutterSliderTooltip(
disabled: true,
),
...
)
```
### Tooltip Direction
To change the direction of the tooltip, you can use `direction`
```dart
FlutterSlider(
...
tooltip: FlutterSliderTooltip(
direction: FlutterSliderTooltipDirection.right,
),
...
)
```
### Tooltip Position Offset
By default tooltip alignment is center, but you can modify it's `top`, `left`, `right` and `bottom` by using `positionOffset`
```dart
FlutterSlider(
...
tooltip: FlutterSliderTooltip(
positionOffset: FlutterSliderTooltipPositionOffset(
top: -100
),
),
...
)
```
### Always Show Tooltips
Tooltips always displayed if this property is set to `true`.
```dart
FlutterSlider(
...
tooltip: FlutterSliderTooltip(
alwaysShowTooltip: true,
),
...
)
```
## Controls
### Handlers width and height
By default both handlers size are 35 width and height, but you can change this by `handlerWidth` and `handlerHeight`
```dart
FlutterSlider(
...
handlerWidth: 30,
handlerHeight: 30,
...
)
```
### Select By Tap
You can tap on the slider to select it's value.
if slider is range-slider, then the closest handler to the selected point will move to that point
```dart
FlutterSlider(
...
selectByTap: true, // default is true
...
)
```
if you want to move your handlers by touching and moving active TrackBar, you have to set this to `false`
### Jump
By default slider handlers move fluently, if you set `jump` to true, handlers will jump between intervals
```dart
FlutterSlider(
...
jump: true,
...
)
```
### Step
The amount the slider changes on movement can be set using `step` option
```dart
FlutterSlider(
...
step: FlutterSliderStep(step: 1),
...
)
```
### Range Step
If you want to have a non-linear slider with different steps, simply use `rangeStep` feature.
```dart
FlutterSlider(
min: 0,
max: 1000000,
...
step: FlutterSliderStep(
step: 1, // default
isPercentRange: true, // ranges are percents, 0% to 20% and so on... . default is true
rangeList: [
FlutterSliderRangeStep(from: 0, to: 20, step: 10000),
FlutterSliderRangeStep(from: 20, to: 100, step: 200000),
]
),
...
)
```
### Ignore Steps
If your configurations requires that some steps are not available, you can use `ignoreSteps` property.
this property accepts a simple class to define `from` and `to` ranges.
```dart
FlutterSlider(
...
ignoreSteps: [
FlutterSliderIgnoreSteps(from: 8000, to: 12000),
FlutterSliderIgnoreSteps(from: 18000, to: 22000),
],
...
)
```
### Fixed Values
If you want to have an array of fixed items and slide through it, you can use `fixedValues` property. use `FlutterSliderFixedValue` to add your fixed values.
`FlutterSliderFixedValue` has following properties:
1. `percent`: (int) ( between 0..100 inclusive). the position of fixed item
2. `value`: (dynamic) the value of fixed item
* when using `fixedValues`, values of `values` property, must be within 0..100
```dart
FlutterSlider(
...
values: [ 10, 50 ],
fixedValues: [
FlutterSliderFixedValue(percent: 0, value: "1000"),
FlutterSliderFixedValue(percent: 10, value: "10K"),
FlutterSliderFixedValue(percent: 50, value: 50000),
FlutterSliderFixedValue(percent: 80, value: "80M"),
FlutterSliderFixedValue(percent: 100, value: "100B"),
],
...
)
```
using above example, you get `(string) 10K` as `upperValue` or `lowerValue` (depends on handler), when you reach to 10 percent of the slider,
you get `(int) 50000` when you reach 50 percent of the slider and so on...
**when using `fixedValues`, `min` and `max` are ignored**
### Minimum Distance
When using range slider, the minimum distance between two handlers can be defined using `minimumDistance` option
```dart
FlutterSlider(
...
minimumDistance: 300,
...
)
```
### Maximum Distance
This is the opposite of minimum distance, when using range slider, the maximum distance between two handlers can be defined using `maximumDistance` option
```dart
FlutterSlider(
...
maximumDistance: 300,
...
)
```
### Locked Handlers
If you want to lock your handlers by a certain value, you can use `lockHandlers` and `lockDistance` properties
```dart
FlutterSlider(
...
lockHandlers: true,
lockDistance: 50,
...
)
```
### Hatch Mark
You can display a `Hatch Mark` underneath or beside of your slider based on `axis`. In order to display hatch mark you must
use `FlutterSliderHatchMark` class which has following properties:
1. `linesDistanceFromTrackBar`: The distance of lines from slider. can be negative
2. `bigLine`: The widget of big lines in hatch mark
3. `smallLine`: The widget of small lines in hatch mark
4. `linesAlignment`: the direct of lines, `right` or `left` which works as `top` or `bottom` on horizontal slider
5. `density`: The amount of lines per percent. 1 is default. any number less or more than 1 will decrease and increase lines respectively
6. `displayLines`: to display lines. by default is `false` for the sake of optimization
7. `labels`: If you want to display some label or text at certain percent in your hatch mark, you can use `labels`
8. `labelBox`: The widget of label box, however, you can define a widget for each label and have it's own style
9. `labelsDistanceFromTrackBar`: The distance of labels from slider. can be negative
10. `disabled`: to disabled the whole hatchmark ( hide )
**labels alignment is center**
Here is an example:
```dart
FlutterSlider(
...
hatchMark: FlutterSliderHatchMark(
density: 0.5, // means 50 lines, from 0 to 100 percent
labels: [
FlutterSliderHatchMarkLabel(percent: 0, label: Text('Start')),
FlutterSliderHatchMarkLabel(percent: 10, label: Text('10,000')),
FlutterSliderHatchMarkLabel(percent: 50, label: Text('50 %')),
FlutterSliderHatchMarkLabel(percent: 80, label: Text('80,000')),
FlutterSliderHatchMarkLabel(percent: 100, label: Text('Finish')),
],
),
...
)
```
### Centered Origin
If you want the value of your slider originates from center of the slider, then you can use `centeredOrigin` property
```dart
FlutterSlider(
...
centeredOrigin: true
...
...
trackBar: FlutterSliderTrackBar(
activeTrackBar: BoxDecoration(color: trackBarColor)
),
...
...
onDragging: (handlerIndex, lowerValue, upperValue) {
if (lowerValue > (max - min) / 2) {
trackBarColor = Colors.blueAccent;
} else {
trackBarColor = Colors.redAccent;
}
setState(() {});
})
...
)
```
### Touch Size
You can control how big a handler's touch area could be. by default touch size is 25
The range is between 5 to 50
```dart
FlutterSlider(
...
touchSize: 25,
...
)
```
To see the touchable area for handlers, set `visibleTouchArea` to true and test your slider
```dart
FlutterSlider(
...
visibleTouchArea: true,
...
)
```
### Disabled
to disable your slider, you can use `disabled`.
```dart
FlutterSlider(
...
disabled: true,
...
)
```
### RTL
makes the slider `Right To Left`
```dart
FlutterSlider(
...
rtl: true,
...
)
```
## Events
There are 3 events
`onDragStarted`: fires when drag starts
`onDragCompleted` fires when drag ends
`onDragging` keeps firing when dragging
All three of above functions returns three values.
```dart
(int handlerIndex, dynamic lowerValue, dynamic upperValue)
```
First value is `handlerIndex`, which determines the handler. 0 is `Left Handler` and 1 refers to `Right Handler`
```dart
FlutterSlider(
...
onDragging: (handlerIndex, lowerValue, upperValue) {
_lowerValue = lowerValue;
_upperValue = upperValue;
if(handlerIndex == 0)
print(" Left handler ");
setState(() {});
},
...
)
```
## Working with Dates
Working with dates are simple and straightforward. just pass standard unix timestamp as values like so:
```dart
FlutterSlider(
...
values: [
new DateTime(2019,6,1,0,0,0).millisecondsSinceEpoch.toDouble(), // lower date : 2019-06-01
new DateTime(2019,9,1,0,0,0).millisecondsSinceEpoch.toDouble(), // upper date : 2019-09-01
],
min: new DateTime(2019,1,1,0,0,0).millisecondsSinceEpoch.toDouble(), // start date : 2019-01-01
max: new DateTime(2020,1,1,0,0,0).millisecondsSinceEpoch.toDouble(), // finish date : 2020-01-01
step: FlutterSliderStep(step: 86400), // 1 day
...
...
tooltip: FlutterSliderTooltip(
custom: (value) {
DateTime dtValue = DateTime.fromMillisecondsSinceEpoch(value.toInt());
String valueInTime = dtValue.year.toString() + '-' + dtValue.month.toString() + '-' + dtValue.day.toString();
return Text( valueInTime );
}
)
...
)
```
