fromCampaignJson static method

GuideConfig? fromCampaignJson(Map<String, dynamic> json)

Parses a guide from a campaign's JSON, mirroring RN's _parseTemplateConfig (flat templateConfig with templateType tooltip/spotlight).

Implementation

static GuideConfig? fromCampaignJson(Map<String, dynamic> json) {
  final tc = optMap(json, 'templateConfig');
  if (tc == null) return null;
  final type = optString(tc, 'templateType');
  final rawSteps = optList(tc, 'steps') ?? const [];
  final templateId = _optStringOrNull(tc, 'templateId');
  final outsideTap = optString(tc, 'outsideTapBehavior', 'next');

  if (type == 'tooltip') {
    final steps = <TooltipStep>[];
    for (final raw in rawSteps) {
      if (raw is Map) {
        final s = TooltipStep.fromJson(raw.cast<String, dynamic>());
        if (s != null) steps.add(s);
      }
    }
    if (steps.isEmpty) return null;
    return TooltipGuideConfig(
        steps: steps, templateId: templateId, outsideTapBehavior: outsideTap);
  }
  if (type == 'spotlight') {
    final steps = <SpotlightStep>[];
    for (final raw in rawSteps) {
      if (raw is Map) {
        final s = SpotlightStep.fromJson(raw.cast<String, dynamic>());
        if (s != null) steps.add(s);
      }
    }
    if (steps.isEmpty) return null;
    return SpotlightGuideConfig(
        steps: steps, templateId: templateId, outsideTapBehavior: outsideTap);
  }
  return null;
