[FIXED] Flutter error Unable to start the daemon process


Flutter project runs smoothly on my old laptop. But with my new laptop, I can’t run my flutter project in debug mode.

This error

FAILURE: Build failed with an exception.

* What went wrong:

Unable to start daemon process.

This issue may be caused by incorrect configuration of the daemon.

For example, an unrecognized jvm option is used.

See the user manual chapter about daemons at https://docs.gradle.org/5.6.2/userguide/gradle_daemon.html.

Process command line: C:\Program Files (x86)\Java\jre1.8.0_221\bin\java.exe -Xmx1536M -Dfile.encoding=windows-1252 -Duser.country=US -Duser.language=en -Duser. Variant -cp C:\Users\ajoris\.gradle\wrapper\dists\gradle-5.6.2-all\9st6wgf78h16so49nn74lgtbb\gradle-5.6.2\lib\gradle-launcher-5.6.2.jar org.gradle.launcher. daemon.bootstrap.GradleDaemon 5.6.2

Am I missing something in my new laptop settings? Tried clean project, upgrade flutter but always fails. Sorry for being new


The general procedure I use is:

  • Run flutter doctor in terminal
  • If you are using an emulator, make sure you have enough space (often requires a reboot to clean up junk files created by successive deployments)
  • If the gradle file has been modified, we recommend opening it in Android Studio (in your application’s Android folder). If anything is missing, the IDE will prompt you to install the missing dependencies.
    Hope this helps
