I managed to solve this error from this github issue: https://github.com/GeekyAnts/NativeBase/issues/4303.
Apparently the problem is that you need to wrap app elements in <NativeBaseProvider>.
In this example you can see how the native base provider wraps all other providers, if the <NativeBaseProvider> is not at the top, it will throw the error: useTheme must be used within `NativeBaseConfigProvider
export default function App() {
return (
<NativeBaseProvider>
<SafeAreaProvider>
<AuthProvider>
<Navigation colorScheme={colorScheme} />
<StatusBar />
</AuthProvider>
</SafeAreaProvider>
</NativeBaseProvider>
);
}

<Container>
<Header searchBar rounded>
</Header>
<View style={styles.container}>
<Text>Product Container</Text>
<View style={styles.listContainer}>
<FlatList
data={products}
numColumns={2}
renderItem={({item}) => <ProductList
key={item.brand}
item={item}/>}
keyExtractor={item => item.brand}
/>
</View>
</View>
</Container>
wrap all these Container tag and its contents inside...

If the issue is happening in Testing you can simply pass initialWindowMetrics to NativeBaseProvider in your tests.
const inset = {
frame: { x: 0, y: 0, width: 0, height: 0 },
insets: { top: 0, left: 0, right: 0, bottom: 0 },
};
<NativeBaseProvider initialWindowMetrics={inset}>
{children}
</NativeBaseProvider>;
