I have a Flutter project which runs perfectly in v2.3.3. I upgraded the flutter version to 3.0.0 in order to use null safety feature. I solved every errors. However when I ran the project, I got Command PhaseScriptExecution failed with a nonzero exit code error. I couldn't find any reasonable and logical solutions throughout internet. Could you please help me on this issue?

CodePudding user response：

I faced the same issue and resolved it by upgrading a package. Within the spam of warning logs, there was one line that mentioned "Error" instead of "Warning", due to parameter change e.g. in my case for a TextField. I saw the package had an updated version for Flutter 3.0 and reran after upgrading. The warning logs will be still there, but you're app should be running afterwards.

Check for Errors within the Warning Logs thrown by Packages from your pubspec.yaml

I have same issue and I solved in this way:

• Update MacOS
• Update Xcode and command lines tools
• Run flutter pub upgrade, flutter pub get in the project folder
• Delete podfile.lock in ios folder of the project
• Run cd ios, pod repo update, pod install in the project folder
