问题 I want to create text with linear gradient color in react-native, but cannot find a suitable way or package to do this. I tried to use this package : https://github.com/iyegoroff/react-native-text-gradient. But, while trying to run an example with expo, it is giving me the following error : TypeError: Cannot read property 'x' of undefined This error is located at: in RNLinearTextGradient (at App.js:26) in RCTView (at View.js:60) in View (at App.js:17) in App (at registerRootComponent.js:35)

问题 I could really use some help improving the accuracy of the Geofencing feature. If you look at the following screenshots you can see my location and the location of circle and marker which share the same latLng coordiantes and radius as my geofence. Link to the image If I run the following lines within the app.js file: const taskName = "front_door"; const latLng = { latitude: -37.820711, longitude: 144.994264 }; const radius = 5; Permissions.askAsync(Permissions.LOCATION); Location

问题 I am unable to run Location.startGeofencingAsync on standalone devices but it is running perfectly fine on simulator. This function gets triggered on Simulator and I can see the logs within this function but as soon as I switch to standalone device, It does not work. Here is the error I am constantly getting when running on the standalone device Error: Invalid parameter not satisfying: !stayUp || CLClientIsBackgroundable(internal->fClient) || _CFMZEnabled() Any help would be much appreciated.
