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.addMethodDeclaration((MethodDeclaration node) {
    if (node.name.lexeme != 'build') return;

    final String? returnType = node.returnType?.toSource();
    if (returnType != 'Widget') return;

    node.body.visitChildren(_SnackbarVisitor(reporter, code));
  });
}
