SuperTooltip
It is super flexible and allows you to display ToolTips in the overlay of the screen. It gives you more flexibility over the Flutter standard Tooltip
. You have the option to make the whole screen covered with a background color. Tapping on the background closes the Tooltip.
Run this command:
With Flutter:
flutter pub add super_tooltip
This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):
dependencies:
super_tooltip: latest
Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.
Now in your Dart code, you can use:
import 'package:super_tooltip/super_tooltip.dart';
You have to make your Widget a StatefulWidget
and you just need to create a controller to manage state of tooltips, you can do so by defining an instance of a SuperTooltipController
and pass it through to constructor.
final _controller = SuperTooltipController();
child: SuperTooltip(
_controller: tooltipController,
// ...
)
void makeTooltip() {
_controller.showTooltip();
}
You need to wrap SuperTooltip
with a GestureDetector
, MouseRegion
or InkWell
that is responsible for showing and hiding the content. Further handling of the tooltip state can be managed explicitly through a controller
child: GestureDetector(
onTap: () async {
await _controller.showTooltip();
},
child: SuperTooltip(
showBarrier: true,
controller: _controller,
content: const Text(
"Lorem ipsum dolor sit amet, consetetur sadipscing elitr,",
softWrap: true,
style: TextStyle(
color: Colors.white,
),
),
child: Container(
width: 40.0,
height: 40.0,
decoration: const BoxDecoration(
shape: BoxShape.circle,
color: Colors.blue,
),
child: Icon(
Icons.add,
color: Colors.white,
),
),
),
),
SuperTooltip
just need one required argument which is the content. You can pass a child Widget which can be an icon to represent the what should be clicked. As showed in the example below.
SuperTooltip(
content: const Text("Lorem ipsum dolor sit amet, consetetur sadipscing elitr",
softWrap: true,
style: TextStyle(
color: Colors.white,
),
),
child: Container(
width: 40.0,
height: 40.0,
decoration: const BoxDecoration(
shape: BoxShape.circle,
color: Colors.blue,
),
child: Icon(
Icons.add,
color: Colors.white,
),
),
),
Change the background by passing the backgroundColor
.
SuperTooltip(
backgroundColor: Color(0xff2f2d2f),
//....
),
Change Popup direction to TooltipDirection.right
, TooltipDirection.left
, TooltipDirection.bottom
and TooltipDirection.up
SuperTooltip(
popupDirection: TooltipDirection.right,
//...
)
To customize the shape of the popup or apply your own decoration, you can utilize the decorationBuilder
property. This allows you to access the target
property and define a custom shape or decoration for the tooltip.
SuperTooltip(
decorationBuilder:(target){
return ShapeDecoration(
//...
shape: CustomShape(
//...
target: target,
),
);
}
//...
)
If you'd like to keep the user from dismissing the tooltip by clicking on the barrier, you can change showBarrier
to true
which means pressing on the scrim area will not immediately hide the tooltip.
SuperTooltip(
showBarrier: true,
barrierColor: Colors.red,
//...
)
If you'd like to also show blur behind the pop up, you can do that by making the showDropBoxFilter
to true
you must also enable showBarrier
then set sigmaX
and sigmaY
SuperTooltip(
showBarrier: true,
showDropBoxFilter: true,
sigmaX: 10,
sigmaY: 10,
//...
)
If you'd like to simply react to open or close states, you can pass through onHide
or onShow
callbacks to the default constructor.
SuperTooltip(
onDismiss: () {
// Maybe continue tutorial?
},
onShow: () {
// Start animation?
}
),
To hide the tooltip when the user tap the back button. Wrap your GestureDetector
widget with WillPopScope
widget passing a callback function to onWillPop
like the example below
return WillPopScope(
onWillPop: _willPopCallback,
child: GestureDetector(
onTap: () async {
await _controller.showTooltip();
},
// ..
),
);
Create a callback function to dismiss
Future<bool> _willPopCallback() async {
// If the tooltip is open we don't pop the page on a backbutton press
// but close the ToolTip
if (_controller.isVisible) {
await _controller.hideTooltip();
return false;
}
return true;
}
