Anyone has solution for this issue?

[Suraj-Tiwari]

@jsmile1994 do you have enableProguardInReleaseBuilds = false in app/build.gradle?

Use https://github.com/react-native-community/react-native-masked-view library which is now officially supported for android too.
Dependent library is react-native-linear-gradient.
