floating

Picture in Picture management for Flutter. Android only

App configuration

Add android:supportsPictureInPicture="true" line to the <activity> tag in android/src/main/AndroidManifest.xml:

<manifest>
   <application>
        <activity
            android:name=".MainActivity"
            android:supportsPictureInPicture="true"
            ...

Widget

This package provides a helper PiPSwitcher widget for switching the displayed widgets according to current PiP status. Use it like so:

PiPSwitcher(
    childWhenDisabled: Scaffold(...),
    childWhenEnabled: JustVideo(), 
)

API

PiP mode in desired mode is available only in Android so iOS and web support is not planned until the platforms adds native support for such feature.

Create a Floating instance

final floating = Floating();

Check if PiP is available

final canUsePiP = await floating.isPipAvailable;

PiP may be unavailable because of system settings managed by admin or device manufacturer. Also, the device may have Android version that was released without this feature.

Check if app is in PiP mode

final currentStatus = await floating.pipStatus;

Possible statuses:

Status	Description	Will enable() have an effect?
disabled	PiP is available to use but currently disabled.	Yes
enabled	PiP is enabled. The app can display content but will not receive user inputs until the user decides to bring the app to it's full size.	No
automatic	PiP will be enabled automatically by the OS.	Yes
unavailable	PiP is disabled on given device.	No

Enable PiP mode

Enable PiP right away:

final statusAfterEnabling = await floating.enable(ImmediatePiP());

Enable PiP when the app gets minimized via system gesture:

final statusAfterEnabling = await floating.enable(OnLeavePiP());

To later cancel, use .cancelOnLeavePiP().

When enabled, PiP mode can be toggled off by the user via system UI.

Arguments

aspectRatio:

The default 16/9 aspect ratio can be overridden with custom Rational. Eg. to make PiP square use: .enable(aspectRatio: Rational(1, 1)) or .enable(aspectRatio: Rational.square()).

sourceRectHint:

By default, system will simply use fade animation to tween between full app and PiP. Switching animation can be smoother by using source rect hint (example animation).

Check the example project to see an example of usage.
