Analysis Configuration

Configure the Dart analyzer using the analysis_options.yaml file located at the package root.

Base Configuration: Always include a standard rule set (e.g., package:lints/recommended.yaml or package:flutter_lints/flutter.yaml) using the include: directive.

Strict Type Checks: Enable strict type checks under the analyzer: language: node to prevent implicit downcasts and dynamic inferences. Set strict-casts: true, strict-inference: true, and strict-raw-types: true.

Linter Rules: Explicitly enable or disable specific rules under the linter: rules: node. Use a key-value map (rule_name: true/false) when overriding included rules, or a list (- rule_name) when defining a fresh set. Do not mix list and map syntax in the same rules block.

Formatter Configuration: Configure dart format behavior under the formatter: node. Set page_width (default 80) and trailing_commas (automate or preserve).

Analyzer Plugins: Enable custom diagnostics by adding plugins under the analyzer: plugins: node. Ensure the plugin package is added as a dev_dependency in pubspec.yaml.
