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.addInstanceCreationExpression((InstanceCreationExpression node) {
    if (!_isSvgPictureNode(node)) return;
    if (node.constructorName.name?.name != 'network') return;
    if (_hasNamedArg(node, 'placeholderBuilder')) return;

    // Skip intentionally invisible widgets (width: 0, height: 0).
    final width = _literalDouble(node, 'width');
    final height = _literalDouble(node, 'height');
    if (width == 0.0 && height == 0.0) return;

    reporter.atNode(node);
  });
}
