HELP PLEASE URG

Greetings,

A few days ago, we purchased the source code for a streaming app from Envato, and we are attaching the purchase code. The app runs locally, as does the website, but both display only a blank home screen without any additional content. Below, we have listed the issues we encountered, and we would like to know how to resolve them.

It is evident that strictly following the steps in the documentation leads to various errors.

1. First Step: Running flutter pub get to update dependencies presents multiple issues. Many dependencies are not configured as expected, causing compatibility issues, as seen with init – firebase_core, among others.

2. The Android files, both /gradle and app/gradle, are deprecated and not in the updated format, which causes issues when attempting to run the application.

3. When trying to stabilize the application somewhat and run it on an Android device through Android Studio, multiple issues arise:

   3.1 At startup, the application encounters initialization errors due to the instability of various dependencies. Once the application is somewhat stabilized, it stays on a black screen and only shows the home icon. It displays the carousel loading but without any content or sections.

   3.2 There are console initialization errors and Firebase-related issues, despite having completed the necessary configuration. It shows errors when loading the app_plugin_loader method, preventing the app from executing any other processes, leaving it static.

   This message indicates that Flutter’s app_plugin_loader plugin is currently being applied using the apply script method, which is marked as deprecated and will be removed in future versions.

4. Carousel_slider and Carousel_controller methods are not working together. Due to dependency incompatibility, they operate as if they were in the same class and do not perform their intended function.

5. API errors indicate that some input files in the project are using or overwriting deprecated APIs, which is causing Firebase initialization problems.
