Thanks man!! you saved me a lot of time
const realURI = Platform.select({ android: result.uri, ios: decodeURI(result.uri), })
Thanks bro. As I could not fetch the Sha1 due to the path not being valid.
Thanks ! Be aware that some adaptations are needed to fit with latest version of the image picker but most of the work is already done ^^
Thanks man, you saved my life! 🥇
thanks for your wrapper code syntax, i modified according to my requirements
