In Android Studio, it cannot build the source and got various errors.

Hello, I downloaded RemoteFiles APK and install it in Android Emulator, and it works really nice.

So I tried to modify some codes, so I download the source code and open it with Android Studio.

In my Android Studio Environment, it already installed flutter and dart plugin.

So I tried to build it and run in virtual Android environment but there are too many errors comes out.

the errors look like this.

it seems that the error are related with gradle version so I search it in Google for several hours but there are too many solutions to apply it, and some solutions, causes another errors.
