hidden logo
Features #
The hidden_logo package allows you to add any Flutter widget under the Notch or
the Dynamic Island for iPhones. It can be your brand logo or its simplified version.
They will only be visible for users in certain scenarios, for example when user
takes a screenshot of your app, minimizes it or uses some kind of screen mirroring.
❗No additional checks or manually written conditions are required when using HiddenLogo:
Application running on any other devices not marked as target ones will not be
affected. Currently, the list of target devices only contains all iPhones starting
from iPhone X all the way up to iPhone 16 series.
You can see the List of Target iPhones separated by hardware barrier
type (Notch or Dynamic Island) in the table down below.
It provides precise size constraints for every iPhone. So you don't need to
be worried about the size of your child widget.
Corners of your Dynamic Island widget will be rounded automatically.
Your child widget will only be visible in portrait mode.
Usage #
Wrap your MaterialApp or CupertinoApp with HiddenLogo widget or define
its builder function. Then you have to provide 2 builders for 2 cases:
iPhones with Notch and the ones with Dynamic Island.
@override
Widget build(BuildContext context) {
return MaterialApp(
builder: (context, child) {
return HiddenLogo(
body: child!,
notchBuilder: (context, constraints) {
return MyNotchLogoBuilder();
},
dynamicIslandBuilder: (context, constraints) {
return MyDynamicIslandLogoBuilder();
},
);
},
);
}

The size of your brand logo can be adaptive thanks to constraints provided
by the widget. They define maxWidth and maxHeight where you can draw and remain hidden.
All the existing iPhone variants starting from iPhone X are tested, so the widget
always returns correct max constraints!
Also do not forget to define BorderRadius property for your Notch logo widget,
so it nicely fits under the hardware barrier and non-visible when not intended to.

Recommendations and tips #
❌ Do not place kinky visual trash (especially adds) but only your brand or
application logo. Doing opposite may cause troubles with releasing
your app to the store.
❌ Do not place any important or sensitive information in HiddenLogo widget.
Assume that user don't even see your widget there.
❌ Do not set any on tap callbacks for your widgets that you place under
the hardware barriers. User will not be able to click there.
❌ Do not use HiddenLogo widget if top of the screen in your app already
have many details in app bars. Doing opposite will make it look even more overloaded.
✅ Hide your HiddenLogo widget while splashscreen is displayed. You can achieve this
by setting isShown property to false in HiddenLogo widget.
✅ If your brand's logo is complicated and have many small details you may want to
use simplified version. Or just display its name.
✅ Feel free to slightly animate your child widget if needed. But don't overdo it!
Debugging #
To test visual appearance of your widget when developing you can either
minimize your app or take a screenshot of your app (for ios simulator:
Device → Trigger Screenshot)

About new devices support #
When the new iPhones are released, your logos won't appear on their screens because
the actual shape and size configuration of further devices are unknown in advance.
But the package will be updated as soon as possible when all necessary SDKs are available!
