  "message": "[Tool] Fix null check operator crash in currentPackageConfig (#188454)\n\nThe Flutter tool crashes with a `Null check operator used on a null\nvalue` in sandboxed or package-managed environments (like NixOS or\nstand-alone AOT runs) where the isolate does not provide package\nresolution metadata.\n\nThis change implements:\n\n1. Removing the strict null assertion (`!`) on\n`Isolate.packageConfigSync`.\n\n2. Adding a robust fallback: if null, it attempts to resolve\n`.dart_tool/package_config.json` relative to the current working\ndirectory and then the executing script.\n\n3. If all fail, it throws a clean `ToolExit` prompting the user to run\n`flutter pub get` instead of a raw runtime crash.\n\nFixes https://github.com/flutter/flutter/issues/188449",
