# [10.0.0](https://github.com/react-native-community/react-native-webview/compare/v9.4.0...v10.0.0) (2020-05-26)

### Bug Fixes

* **android:** add missing null check for fileTypes ([#1368](https://github.com/react-native-community/react-native-webview/issues/1368) by [@bengy](https://github.com/bengy)) ([4f0f0af](4f0f0afe70/))
* **gradle:** Load Android Gradle Plugin conditionally ([#1230](https://github.com/react-native-community/react-native-webview/issues/1230) by @SaeedZhiany) ([2639d52](2639d523e9/))
* **iOS:** Trigger _onContentProcessDidTerminate when removing webview from superview ([#1378](https://github.com/react-native-community/react-native-webview/issues/1378) by [@pmusaraj](https://github.com/pmusaraj)) ([9240536](9240536afa/))
* **windows:** Fix windows local asset path ([#1335](https://github.com/react-native-community/react-native-webview/issues/1335) by [@kaiguo](https://github.com/kaiguo)) ([20a3f90](20a3f90c0f/))
* **windows:** Fixes ScriptNotify and InvokeScript ([#1354](https://github.com/react-native-community/react-native-webview/issues/1354) by [@benhamlin](https://github.com/benhamlin)) ([81e0360](81e0360ede/))

### BREAKING CHANGES

* **gradle:** The Android Gradle plugin is only required when opening the project stand-alone, not when it is included as a dependency. By doing this, the project opens correctly in Android Studio, and it can also be consumed as a native module dependency from an application project without affecting the app project (avoiding unnecessary downloads/conflicts/etc).

Also moved getExtOrDefault to buildScript block to able to use everywhere in the file

This change shouldn't break any apps, but we are marking it as a breaking change in case there are some use cases we've missed.
