What are @gorhom/bottom-sheet's main functionalities?

Basic Bottom Sheet

This code demonstrates how to create a basic bottom sheet with three snap points (collapsed, half-expanded, and fully expanded). The bottom sheet can be opened by pressing a button.

```jsx
import React, { useRef } from 'react';
import { View, Text, Button } from 'react-native';
import BottomSheet from '@gorhom/bottom-sheet';

const App = () => {
  const bottomSheetRef = useRef(null);
  return (
    <View style={{ flex: 1 }}>
      <Button title="Open Bottom Sheet" onPress={() => bottomSheetRef.current?.expand()} />
      <BottomSheet ref={bottomSheetRef} snapPoints={[0, '50%', '100%']}>
        <View style={{ flex: 1, alignItems: 'center' }}>
          <Text>Bottom Sheet Content</Text>
        </View>
      </BottomSheet>
    </View>
  );
};

export default App;
```

Custom Handle Component

This code demonstrates how to use a custom handle component for the bottom sheet. The custom handle can be styled and customized as needed.

```jsx
import React, { useRef } from 'react';
import { View, Text, Button } from 'react-native';
import BottomSheet, { BottomSheetHandle } from '@gorhom/bottom-sheet';

const CustomHandle = () => (
  <View style={{ padding: 20, backgroundColor: 'lightgray' }}>
    <Text>Custom Handle</Text>
  </View>
);

const App = () => {
  const bottomSheetRef = useRef(null);
  return (
    <View style={{ flex: 1 }}>
      <Button title="Open Bottom Sheet" onPress={() => bottomSheetRef.current?.expand()} />
      <BottomSheet ref={bottomSheetRef} snapPoints={[0, '50%', '100%']} handleComponent={CustomHandle}>
        <View style={{ flex: 1, alignItems: 'center' }}>
          <Text>Bottom Sheet Content</Text>
        </View>
      </BottomSheet>
    </View>
  );
};

export default App;
```

Bottom Sheet with FlatList

This code demonstrates how to use a FlatList inside the bottom sheet. This is useful for displaying a list of items within the bottom sheet.

```jsx
import React, { useRef } from 'react';
import { View, Text, Button, FlatList } from 'react-native';
import BottomSheet from '@gorhom/bottom-sheet';

const App = () => {
  const bottomSheetRef = useRef(null);
  const data = Array.from({ length: 50 }, (_, i) => `Item ${i + 1}`);
  return (
    <View style={{ flex: 1 }}>
      <Button title="Open Bottom Sheet" onPress={() => bottomSheetRef.current?.expand()} />
      <BottomSheet ref={bottomSheetRef} snapPoints={[0, '50%', '100%']}>
        <FlatList
          data={data}
          keyExtractor={(item) => item}
          renderItem={({ item }) => (
            <View style={{ padding: 20 }}>
              <Text>{item}</Text>
            </View>
          )}
        />
      </BottomSheet>
    </View>
  );
};

export default App;
```

Compared to @gorhom/bottom-sheet, it offers similar functionalities but may require more setup due to its dependencies on Reanimated and Gesture Handler.

While it offers similar functionalities to @gorhom/bottom-sheet, it is more focused on providing a general modal solution rather than just bottom sheets.
