Detect react-native-edge-to-edge and bypass setShouldMimicIOSBehavior

[zoontek]

Description

This PR brings react-native-edge-to-edge detection to react-native-avoid-softinput.

The future of Android is edge-to-edge, and to make the React Native developer experience seamless in this regard, the ecosystem needs to transition from “opaque system bars by default” to “edge-to-edge by default.”

To prevent library authors from implementing their own edge-to-edge solutions—which could interfere with other libraries—and because it’s not possible to reliably detect if edge-to-edge is already enabled on Android, we have collaborated with Expo to create a library that handles this functionality and is detectable using a simple helper: react-native-is-edge-to-edge (250 bytes minified - no gzip).

This approach allows you to bypass certain options and props (in this case, it removes the need to call setShouldMimicIOSBehavior entirely, which is dangerous as setShouldMimicIOSBehavior(false) currently breaks edge-to-edge).

After digging a bit into your code, I think this is the only required change. setShouldMimicIOSBehavior calls setShouldHandleInsets, which only call WindowCompat.setDecorFitsSystemWindows(activity.window, decorFitsSystemWindows) (doesn't even update a module level variable or else), something already handled by react-native-edge-to-edge that call WindowCompat.setDecorFitsSystemWindows(activity.window, false) immediately at app start.

This will also print a warning to inform the users that calling this function is not needed anymore in such case:

shoudMimic value is ignored when using react-native-edge-to-edge

PS: If you want to keep the call, I can update the TS to be:

function setShouldMimicIOSBehavior(shouldMimic: boolean) {
  if (Platform.OS !== 'android') {
    return;
  }
  if (__DEV__) {
    controlEdgeToEdgeValues({ shouldMimic });
  }

  module.setShouldMimicIOSBehavior(EDGE_TO_EDGE || shouldMimic);
}

heeey, looks cool! I'll check it today's evening

Looks good! Thx for the contribution! I'll need to mention in docs that react-native-edge-to-edge should now be recommended way and will deprecate shouldMimicIOSBehavior before releasing new version (I hope to find some time this week)

This is now released in v7.0.0 🥳
