Answer 1

have you tried a clean build with flutter clean ? and could you also post more of your error and code?

Answer 2

Try to empty cache "C:\Users\dell.gradle\caches" and re-run the project. You should also check for Event log error when building the project.

Answer 3

In your android studio, cd to android directory then run from terminal: gradlew clean gradlew build and then run the application. If it wont work try flutter clean. Also delete the.gradle folder in Users directory. it will take some time but it will run.

Answer 4

Run

flutter run -v

so you can see which part is taking much time. In my case it was Downloading https://services.gradle.org/distributions/gradle-7.4-all.zip if you have the same problem check this
