suggestFromChain static method

List<FixSuggestion> suggestFromChain(LayoutDecision decision, List<ConstraintChainLink> chain)

Generate suggestions from a constraint chain analysis.

This uses the full chain of constraints from root to the overflowing widget to identify WHERE the constraint became problematic.

Implementation

static List<FixSuggestion> suggestFromChain(
  LayoutDecision decision,
  List<ConstraintChainLink> chain,
) {
  final suggestions = suggest(decision);

  // Find the link where unbounded constraints were introduced
  for (int i = 0; i < chain.length; i++) {
    final link = chain[i];
    if (link.constraints is BoxConstraints &&
        ((link.constraints as BoxConstraints).maxWidth == double.infinity ||
            (link.constraints as BoxConstraints).maxHeight ==
                double.infinity)) {
      final widgetName = link.widgetType;
      suggestions.insert(
        0,
        FixSuggestion(
          description: 'Unbounded constraint introduced at $widgetName '
              '(level $i in the chain)',
          codeHint: 'Add constraints to $widgetName or its parent',
          confidence: 0.85,
          priority: 0,
          category: FixCategory.constrainDimensions,
        ),
      );
      break;
    }
  }

  return suggestions;
