Job ID: 37582169

Budget: $250 – $750 USD

Hello Flutter developers,
I am new to a certain company, and the previous Flutter developer was working on the main product (mobile app) of the company for like two years, and when the time came for his resignation, he just pushed the project to GitHub. Now, when I came here, and just cloned the project and tried to run it, it kept giving me the "Gradle version is incompatible with Java version". I've been for like two days trying to fix the version's errors, I tried updating the used packages versions but nothing really worked. Whenever I fix a certain error, another is displayed.
So, I am looking for a freelancer who can help me fix this error in my project.

Skills and experience needed:
- Extensive knowledge and experience with Gradle and Java
- Extensive knowledge of Flutter framework and Dart SDK
