# [10.0.0](react-native-webview/react-native-webview@v9.4.0...v10.0.0) (2020-05-26)

### Bug Fixes

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

### 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.
