Renamed parameters titleAlignment
to titleTextAlign
and descriptionAlignment
to descriptionTextAlign
to correspond it more with the TextAlign property.titleAlignment
and descriptionAlignment
will be used for widget alignment.
Before:
Showcase(
titleAlignment: TextAlign.center,
descriptionAlignment: TextAlign.center,
),
After:
Showcase(
titleTextAlign: TextAlign.center,
descriptionTextAlign: TextAlign.center,
),
-
Add dependency to
pubspec.yaml
Get the latest version in the 'Installing' tab on pub.dev
dependencies:
showcaseview: <latest-version>
- Import the package
import 'package:showcaseview/showcaseview.dart';
- Register a
ShowCaseView
widget.
void initState() {
super.initState();
ShowcaseView.register(scope: scopeName);
);
- Adding a
Showcase
widget.
GlobalKey _one = GlobalKey();
GlobalKey _two = GlobalKey();
GlobalKey _three = GlobalKey();
...
Showcase(
key: _one,
title: 'Menu',
description: 'Click here to see menu options',
child: Icon(
Icons.menu,
color: Colors.black45,
),
),
Showcase.withWidget(
key: _three,
height: 80,
width: 140,
targetShapeBorder: CircleBorder(),
container: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
...
],
),
child: ...,
),
- Starting the
ShowCase
:
- If you have a single showcase, then you can start the
ShowCaseView
using the code below:
someEvent() {
ShowCaseView.get().startShowCase([_one, _two, _three]);
}
- If you have multiple ShowcaseViews, then you can start the
ShowCaseView
using the code below, which is recommended:
someEvent() {
ShowCaseView.getNamed(scopeName).startShowCase([_one, _two, _three]);
}
If you want to start the ShowCaseView
as soon as your UI built up then use below code:
WidgetsBinding.instance.addPostFrameCallback((_) =>
ShowCaseWidget.of(context).startShowCase([_one, _two, _three])
);
If you have some animation or transition in your UI and you want to start the ShowCaseView
after
that then use below code:
WidgetsBinding.instance.addPostFrameCallback((_) =>
ShowCaseWidget.of(context).startShowCase([_one, _two, _three], delay: "Animation Duration")
);
Check out the example app in the example directory or the 'Example' tab on pub.dartlang.org for a more complete example.
To show multiple showcase at the same time provide same key to showcase. Note: auto scroll to showcase will not work in case of the multi-showcase and we will use property of first initialized showcase for common things like barrier tap and colors.
GlobalKey _one = GlobalKey();
...
Showcase
(
key: _one,
title: 'Showcase one',
description: 'Click here to see menu options',
child: Icon(
Icons.menu,
color: Colors.black45,
),
),
Showcase(
key: _one,
title: 'Showcase two',
description: 'Click here to see menu options',
child: Icon(
Icons.menu,
color:Colors.black45,
),
),
Auto Scrolling to active showcase feature will not work properly in scroll views that renders widgets on demand(ex, ListView, GridView).
In order to scroll to a widget it needs to be attached with widget tree. So, If you are using a scrollview that renders widgets on demand, it is possible that the widget on which showcase is applied is not attached in widget tree. So, flutter won't be able to scroll to that widget.
So, If you want to make a scroll view that contains less number of children widget then prefer to use SingleChildScrollView.
If using SingleChildScrollView is not an option, then you can assign a ScrollController to that scrollview and manually scroll to the position where showcase widget gets rendered. You can add that code in onStart method of ShowCaseWidget
.
Example:
// This controller will be assigned to respected sctollview.
final _controller = ScrollController();
ShowCaseView.register
(
onStart: (index, key) {
if(index == 0) {
WidgetsBinding.instance.addPostFrameCallback((_) {
// If showcase widget is at offset 1000 in the listview.
// If you don't know the exact position of the showcase widget,
// You can provide nearest possible location.
//
// In this case providing 990 instead of 1000 will work as well.
_controller.jumpTo(1000);
});
}
},
);
You can create a custom showcase widget using Showcase.withWidget
:
Showcase.withWidget
(
key: _customKey,
height: 80,
width: 140,
targetShapeBorder: CircleBorder(),
container: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text("This is a custom widget!", style: TextStyle(color: Colors.white)),
SizedBox(height: 10),
Text("You can add any content here.", style: TextStyle(color: Colors.white)),
],
),
child: FloatingActionButton(
onPressed: () {},
child: Icon(Icons.add),
),
)
You can add action buttons to your tooltips to enhance user interaction:
Showcase
(
key: _actionKey,
title: 'Profile',
description: 'Tap to view your profile',
tooltipActions: [
TooltipActionButton(
type: TooltipActionButtonType.next,
name: 'NEXT',
onTap: () {
// Custom action when next is pressed
print("Next pressed");
},
),
TooltipActionButton(
type: TooltipActionButtonType.skip,
name: 'SKIP',
),
],
tooltipActionConfig: TooltipActionConfig(
position: TooltipActionPosition.outside,
alignment: MainAxisAlignment.center,
),
child: CircleAvatar(
child: Icon(Icons.person)
,
)
,
)
Create custom action buttons with TooltipActionButton.custom
:
Showcase
(
key: _customActionKey,
title: 'Custom Actions',
description: 'This showcase has custom action buttons',
tooltipActions: [
TooltipActionButton.custom(
button: Container(
padding: EdgeInsets.symmetric(horizontal: 10, vertical: 4),
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.circular(8),
),
child: Row(
children: [
Icon(Icons.arrow_forward, color: Colors.white, size: 18),
SizedBox(width: 5),
Text('Continue', style: TextStyle(color: Colors.white)),
],
),
),
onTap: () {
// Custom action
},
),
],
child: ListTile(
leading: Icon(Icons.star),
title: Text('Featured Item'),
),
)
Add a floating action widget that appears during the showcase:
Showcase
(
key: _floatingKey,
title: 'Swipe Gesture',
description: 'Swipe left or right to navigate',
floatingActionWidget: (context) => Container(
width: 200,
height: 100,
padding: EdgeInsets.all(10),
margin: EdgeInsets.only(bottom: 50),
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(10),
boxShadow: [
BoxShadow(color: Colors.black26, blurRadius: 10, offset: Offset(0, 5))
],
),
child: Column(
children: [
Icon(Icons.swipe, size: 40),
Text('Swipe to continue', style: TextStyle(fontWeight: FontWeight.bold)),
Text('Use your finger to navigate between items'),
],
),
),
child: Card(
child: ListTile(
title: Text('Swipeable Item'),
subtitle: Text('Try swiping this item'
)
,
)
,
)
,
)
