Usage Example

Step 1: Create Custom Screen and Wrapper

• In your app, create a FileUploadScreenWrapper file which will wrap the FileUploadScreen within the ChatroomContextProvider so that the callbacks becomes accessible inside of the FileUploadScreen.
• Create fileUploadStyles for customisation and call the setFileUploadStyle to set the customisation.

FileUploadScreen

import {
  FileUpload,
  useInputBoxContext,
} from "@likeminds.community/feed-rn-core";

const FileUploadScreen = ({ route }) => {
  const { handleGallery, handleCamera } = useInputBoxContext();

  // customised handleGallery callback
  const customHandleGalleryProp = (type) => {
    console.log("do something before gallery handle");
    handleGallery(type);
    console.log("do something after gallery handle");
  };

  // customised handleGallery callback
  const customHandleCameraProp = (type) => {
    console.log("do something before camera handle");
    handleCamera(type);
    console.log("do something after camera handle");
  };

  const fileUploadStyles = {
    selectedImageBorderColor: "red",
  };

  // like list screen customisation
  if (fileUploadStyles) {
    STYLES.setFileUploadStyle(postLikesListStyles);
  }
  return (
    <FileUpload
      handleGallery={customHandleGalleryProp}
      handleCamera={customHandleCameraProp}
    />
  );
};

export default FileUploadScreen;

FileUploadScreenWrapper

import { FileUploadScreen } from "<<path_to_FileUploadScreen.tsx>>";
import { ChatroomContextProvider } from "@likeminds.community/chat-rn-core/ChatSX/context";

function FileUploadScreenWrapper() {
  return (
    <ChatroomContextProvider>
      <FileUploadScreen />
    </ChatroomContextProvider>
  );
}

export default FileUploadScreenWrapper;

Step 2: Add the Custom Screen in App.tsx

• In your App.tsx, create a Stack.Navigator in the NavigationContainer wrapped by LMOverlayProvider.
• Add FileUploadScreenWrapper as a Stack screen in your NavigationContainer.

App.tsx

import {
  FILE_UPLOAD,
  LMOverlayProvider,
  STYLES,
} from "@likeminds.community/feed-rn-core";
import { FileUploadScreenWrapper } from "<<path_to_FileUploadScreenWrapper.tsx>>";
import { NavigationContainer } from "@react-navigation/native";
import { createNativeStackNavigator } from "@react-navigation/native-stack";

export const App = () => {
  const Stack = createNativeStackNavigator();
  return (
    <LMOverlayProvider
      myClient={myClient} // pass in the LMChatClient created
      apiKey={apiKey} // pass in the API Key generated
      userName={userName} // pass in the logged-in user's name
      userUniqueId={userUniqueID} // pass in the logged-in user's uuid
    >
      <NavigationContainer ref={navigationRef} independent={true}>
        <Stack.Navigator screenOptions={{ headerShown: false }}>
          return (
          <Stack.Screen
            options={{ gestureEnabled: Platform.OS === "ios" ? false : true }}
            name={FILE_UPLOAD}
            component={FileUploadScreenWrapper}
          />
        </Stack.Navigator>
      </NavigationContainer>
    </LMOverlayProvider>
  );
};
