Static Methods
-
fromNativeValue(
String? value) → WebViewFeature? - Gets a possible WebViewFeature instance from a native value.
-
fromValue(
String? value) → WebViewFeature? - Gets a possible WebViewFeature instance from String value.
-
isFeatureSupported(
WebViewFeature feature) → Future< bool> -
Return whether a feature is supported at run-time. On devices running Android version
Build.VERSION_CODES.LOLLIPOP
and higher, this will check whether a 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 returnfalse
. -
isStartupFeatureSupported(
WebViewFeature startupFeature) → Future< bool> -
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 returnfalse
