Fix FileSystemException

✅ Solution

FileSystemException in Flutter typically arises when the app tries to access or modify a file or directory that doesn't exist or lacks the necessary permissions. To resolve this, first ensure the file path is correct and that the target directory exists; create it if needed using `Directory(path).create(recursive: true)`. Subsequently, verify that your app has the required read/write permissions for the file or directory, especially on Android or iOS.
