FluentDocument.fromJson constructor

FluentDocument.fromJson(Map<String, dynamic> json, { FluentPluginRegistry? registry, })

Creates a FluentDocument from a JSON map (result of jsonDecode). Supports both the new format (with "nodes" and "settings") and the legacy format (Root JSON directly).

Implementation

factory FluentDocument.fromJson(
  Map<String, dynamic> json, {
  FluentPluginRegistry? registry,
}) {
  FNodeJsonConverter.activeRegistry = registry;
  try {
    if (json.containsKey('nodes') && json.containsKey('settings')) {
      final root = Root.fromJson(json['nodes'] as Map<String, dynamic>);
      final doc = FluentDocument(content: root, registry: registry);
      final settings = json['settings'] as Map<String, dynamic>;

          (settings['lineHeight'] as num?)?.toDouble() ??
          doc.pendingLineHeight;

          (settings['spacingBefore'] as num?)?.toDouble() ??
          doc.pendingSpacingBefore;

          doc.pendingSpacingAfter;
      doc.pendingFontFamily =
          settings['fontFamily'] as String? ?? doc.pendingFontFamily;

      final comments = json['comments'];
      if (comments is List && doc.commentProvider != null) {
        doc.commentProvider!.importComments(
          comments.map((e) => e as Map<String, dynamic>).toList(),
