runWithReporter method

@override void runWithReporter(SaropaDiagnosticReporter reporter, SaropaContext context)

Override this method to implement your lint rule.

Use context to register callbacks for AST node types:

context.addMethodInvocation((node) {
  if (condition) {
    reporter.atNode(node);
  }
});

Implementation

@override
void runWithReporter(
  SaropaDiagnosticReporter reporter,
  SaropaContext context,
) {
  context.addMethodInvocation((MethodInvocation node) {
    final String method = node.methodName.name;
    if (method != 'setVolume' && method != 'play') return;
    if (!fileImportsPackage(node, PackageImports.audioplayers)) return;

    final Expression? value = method == 'setVolume'
        ? node.argumentList.arguments.firstOrNull
        : _namedArg(node, 'volume');
    if (value == null) return;

    final num? literal = _numericLiteral(value);
    if (literal == null || literal <= 1.0) return;

    reporter.atNode(value);
  });
}
