Configuring Analysis Options

Control static analysis by placing an analysis_options.yaml file at the root of your package.

• Enforce Strict Type Checks: Always enable strict-casts, strict-inference, and strict-raw-types in the analyzer section to catch implicit dynamic casts and un-inferred types at compile time.
• Configure Formatting: Define dart format rules within the formatter section (e.g., page_width and trailing_commas).
• Exclude Generated Code: Use the exclude key to ignore generated files (e.g., **/*.g.dart, **/*.freezed.dart) to prevent false positives.
