Affected Platform(s)

• Android
• iOS
• Electron
• Web

Current Behavior

On iOS, I leave space for the iPhone X notch & iPhone 6 status bar using <meta name="viewport" content="viewport-fit=cover" /> along with env(safe-area-inset-top), as described in #2100 .

I would love to do the same thing in Android, however it appears that overlaying the status bar via StatusBar.setOverlaysWebView({ overlay: true }) does not affect env(safe-area-inset-top) in the CSS. env(safe-area-inset-*) has officially been supported since Chrome 69 (announcement) though how extensively I don’t know.

Expected Behavior

I would expect env(safe-area-inset-top) to include the height of the status bar if it is overlaid.

Reproduction Steps

    // Display content under transparent status bar (Android only)
    StatusBar.setOverlaysWebView({
      overlay: true
    });

Other Technical Details

npm --version output: 6.14.4

node --version output: v12.16.1

Other Information

If fixing env(safe-area-inset-top) is not possible, I would be satisfied being able to access the safe area insets via a Plugin, or injected CSS variables (e.g. --android-safe-area-inset-top or similar).

I’m developing a plugin that sends the device insets, at the moment works only on android, and send only top, its for a emergency. https://www.npmjs.com/package/capacitor-insets-plugin

const { StatusBar, InsetsPlugin } = Plugins;

StatusBar.setOverlaysWebView({ overlay: true });
StatusBar.setStyle({ style: StatusBarStyle.Dark });

InsetsPlugin.top()
    .then((resp: { value: number }) => {
        document.documentElement.style.setProperty('--top-inset', `${resp.value}px`);
    });

@haschu Nope. Tons of apps do this, seems very common - but still haven’t found a way with Capacitor/Ionic
