I have been working with the react-native-gradient and I am getting the following error regarding the package.
Invariant Violation: requireNativeComponent: "BVLinearGradient" was not found in the UIManager.
This error is located at:

import * as Animatable from "react-native-animatable";
import LinearGradient from "react-native-linear-gradient";
import MaterialIcons from "react-native-vector-icons/MaterialIcons";
import { useTheme } from "@react-navigation/native";
const SignupLogin = ({ navigation }) => {
const { colors } = useTheme();
return (
<View style={styles.container}>
.....
<View style={styles.button}>
<TouchableOpacity onPress={() => navigation.navigate("sign-in")}>
<LinearGradient
colors={["#0831d4", "#0131ab"]}
style={styles.signIn}
>
<Text style={styles.textSign}>Get started</Text>
<MaterialIcons name="navigate-next" color="#fff" size={20} />
</LinearGradient>
.....
</View>
);
};
export default SignupLogin;
It is simple navigation between footer sign-in and sign-up menus and the App.js and the rest of the files are in the standard method of coding.
confirm you install react-native-linear-gradient
yarn add react-native-linear-gradient
in ios confirm ios/podfile has this line
pod 'BVLinearGradient', :path => '../node_modules/react-native-linear-gradient'
then run pod install in ios folder
if you're using windows & react-native cli (not expo):
1- in android/settings.gradle, check if
include ':react-native-linear-gradient' project(':react-native-linear-gradient').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-linear-gradient/android')
exist .. if not, add them
2- in android/app/build.gradle, check if
implementation project(':react-native-linear-gradient')
exists in dependecies{ ... } .. if not, add it
3- in android/app/src/main/java/com/{YOUR_APP_NAME}/MainApplication.java , find
@Override protected List getPackages() { ....}
Then replace the comment // packages.add(new MyReactNativePackage());
with => packages.add(new LinearGradientPackage());
It worked for me .. Hope it works for you as well
