isStartupFeatureSupported static method

Future<bool> isStartupFeatureSupported(
  1. WebViewFeature startupFeature
)

Return whether a startup feature is supported at run-time. On devices running Android version Build.VERSION_CODES.LOLLIPOP and higher, this will check whether a startup feature is supported, depending on the combination of the desired feature, the Android version of device, and the WebView APK on the device. If running on a device with a lower API level, this will always return false.

Note: This method is different from isFeatureSupported and this method only accepts startup features. Please verify that the correct feature checking method is used for a particular feature.

Note: If this method returns false, it is not safe to invoke the methods requiring the desired feature. Furthermore, if this method returns false for a particular feature, any callback guarded by that feature will not be invoked.
