Usage

Create Render Option: To render Embedded objects within RTE create renderOption as follows:

Utils.renderContents(rteArray, localJsonObj, (embeddedObject, metadata) -> {
    switch (metadata.getStyleType()) {
        case BLOCK:
           String title = embeddedObject.getString("title");
           String multi_line = embeddedObject.getString("multi_line");
           return "<p>" + title + "</p><span>" + multi_line + "</span>";
        case INLINE:
           String titleInline = embeddedObject.getString("title");
           String mlInline = embeddedObject.getString("multi_line");
           return "<p>" + titleInline + "</p><span>" + mlInline + "</span>";
        case LINKED:
           String titleLinked = embeddedObject.getString("title");
           String mlLinked = embeddedObject.getString("multi_line");
           return "<p>" + titleLinked + "</p><span>" + mlLinked + "</span>";
        case DISPLAY:
           String titleDiplayable = embeddedObject.getString("title");
           String mlDiplayable = embeddedObject.getString("multi_line");
           return "<p>" + titleDiplayable + "</p><span>" + mlDiplayable + "</span>";
       default:
           return null;
   }

Using Contentstack Utils from Contentstack Dart SDK

Fetch entry/entries including embedded using Contentstack SDK

    import 'package:contentstack/contentstack.dart' as contentstack;
    final stack = contentstack.Stack(apiKey, deliveryToken, environment);
    final entry = stack.contentType('contentTypeUid').entry(entryUid: 'entryUid');
    entry..includeEmbeddedItems();
    await entry.fetch().then((response) {
        const keyPath = [ "rich_text_editor", "global_rich_multiple.group.rich_text_editor"]
        final jsonObject = response['entry'];
        Utils.render(jsonObject, keyPath, Option);
    }).catchError((error) {
        print(error.message.toString());
    });

Fetch multiple entries including embedded object and render RTE fields

    import 'package:contentstack/contentstack.dart' as contentstack;
    final stack = contentstack.Stack(apiKey, deliveryToken, environment);
    final query = stack.contentType('contentTypeUid').entry().query();
    await query.find().then((response) {
        var entries = response['entries'];
        const keyPath = ["rich_text_editor", "global_rich_multiple.group.rich_text_editor"]
        entries.forEach((entry){
            Utils.render(entry, keyPath, Option);
        })
    }).catchError((error) {
        print(error.message.toString());
    });
