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) {
    if (node.methodName.name != 'toString') return;

    final Expression? target = node.target;
    if (target == null) return;

    final DartType? type = target.staticType;
    if (type != null && _staticTypeIsFuture(type)) {
      reporter.atNode(node);
    }
  });

  context.addInterpolationExpression((InterpolationExpression node) {
    final Expression expr = node.expression;
    final DartType? type = expr.staticType;
    if (type != null && _staticTypeIsFuture(type)) {
      reporter.atNode(node);
    }
  });
}
