solution
```go to the gradle-wrapper.properties located under android>>gradle/wrapper
and change the gradle version to 6.3 (in my case it was 5.5)
It was like this:
distributionUrl=https://services.gradle.org/distributions/gradle-5.5-all.zip
Changed to this:
distributionUrl=https://services.gradle.org/distributions/gradle-6.3-all.zip
Compile and it should work.```
