Modifying Files Outside Workspace

If you modify files outside your workspace, you may see a warning:

You are modifying a file outside of your open folders

This warning is to help some common situations that can cause problems, such as:

• Accidentally modifying files in your pub cache folder after jumping to the definition of a class This could cause errors if you alter the package code in your pub cache, as other users would not have your modifications
• Modifying files in packages referenced with path that might not be code you intended to modify

If you would prefer not to see this warning, you can prevent it using the dart.warnWhenEditingFilesOutsideWorkspace setting.
