The inspiration behind the package was actually a need for a slide transition like spotify (iOS) Unfortunately, I couldn’t find any efficient package, so I literally banged my fist on the table, rolled up my sleeves and created my own solution. Through this package I could better understand some principles of flutter animation :)
Installation
Add this to your package's pubspec.yaml file:
dependencies:
we_slide: ^2.4.0
Basic Example
https://dartpad.dev/?id=6a833cba62679260bf1a556a4fdc9043
import 'package:we_slide/we_slide.dart';
final _colorScheme = Theme.of(context).colorScheme;
final double _panelMinSize = 70.0;
final double _panelMaxSize = MediaQuery.of(context).size.height / 2;
return Scaffold(
backgroundColor: Colors.black,
body: WeSlide(
panelMinSize: _panelMinSize,
panelMaxSize: _panelMaxSize,
body: Container(
color: _colorScheme.background,
child: Center(child: Text("This is the body 💪")),
),
panel: Container(
color: _colorScheme.primary,
child: Center(child: Text("This is the panel 😊")),
),
panelHeader: Container(
height: _panelMinSize,
color: _colorScheme.secondary,
child: Center(child: Text("Slide to Up ☝️")),
),
),
);

panelBorderRadiusBegin | double | Set this value to create a border radius over panel. When panelBorderRadiusBegin is diffrent from panelBorderRadiusEnd and the panel is slide up, this create an animation border over panel. By default is 0.0 |
panelBorderRadiusEnd | double | Set this value to create a border radius over panel. When panelBorderRadiusBegin is diffrent from panelBorderRadiusEnd and the panel is slide up, this create an animation border over panel. By default is 0.0 |
bodyBorderRadiusBegin | double | Set this value to create a border radius over body. When bodyBorderRadiusBegin is diffrent from bodyBorderRadiusEnd and the panel is slide up, this create an animation border over body. By default is 0.0 |
bodyBorderRadiusEnd | double | Set this value to create a border radius over body. When bodyBorderRadiusBegin is diffrent from bodyBorderRadiusEnd and the panel is slide up, this create an animation border over body. By default is 0.0 |
bodyWidth | double | This is the value that set the body width. By default is MediaQuery.of(context).size.width |
parallaxOffset | double | Set this value to create a parallax effect when the panel is slide up. By default is 0.1 |
footerHeight | double | This is the value that set the footer height. by default is 60.0 |
appBarHeight | double | This is the value that set the appbar height. by default is 80.0 |
overlayOpacity | double | This is the value that defines opacity overlay effect bethen body and panel. |
blurSigma | double | This is the value that creates an image filter that applies a Gaussian blur. |
transformScaleBegin | double | This is the value that defines transform scale begin effect. By default is 1.0 |
transformScaleEnd | double | This is the value that defines transform scale end effect. By default is 0.9 |
overlayColor | color | This is the value that defines overlay color effect. By default is Colors.black |
blurColor | color | This is the value that defines blur color effect. By default is Colors.black |
backgroundColor | color | This is the value that defines background color. By default is Colors.black end should be the same as body |

overlay | bool | This is the value that defines if you want to enable overlay effect. By default is false |
blur | bool | This is the value that defines if you want to enable Gaussian blur effect. By default is false |
animateDuration | bool | This is the value that sets the duration of the animation. By default is 300 milliseconds |
isDismissible | bool | This parameter specifies whether the panelwill be dismissed when user taps on the screen |
controller | WeSlideController | This object used to control animations, using methods like hide or show to display panel and footer or check if is visible with variable isOpened |
fadeSequence | List<TweenSequenceItem<double>> | This is the value that create a fade transition over panel header |
isUpSlide | bool | This is the value that need up sliding panel if you want to enable Slide up through panel. By default is true |
