Deserialization

VideoEditor SDK for Flutter supports serialization and deserialization, allowing your users to save and revise their work at any time.

Loading a serialization#

To restore a previously saved state, we first need to retrieve the serialization. For this example, we have a local serialization file that should be used.

To open the editor with the selected serialization, you need to pass it to the VESDK.openEditor method as the serialization parameter.


import 'dart:convert';

import 'package:catalog/models/code_example.dart';
import 'package:flutter/services.dart';
import 'package:video_editor_sdk/video_editor_sdk.dart';

class VideoDeserializationExample extends CodeExample {
  @override
  void invoke() async {
    try {
      // Load a serialization from the assets folder.
      final serializationString =
          await rootBundle.loadString("assets/video_serialization.json");
      final serialization = jsonDecode(serializationString);

      // Add a video from the assets directory.
      final video = Video("assets/Skater.mp4");

      // Open the video editor and handle the export as well as any occurring errors.
      final result =
          await VESDK.openEditor(video, serialization: serialization);

      if (result != null) {
        // The user exported a new video successfully and the newly generated video is located at `result.video`.
        print(result.video);
      } else {
        // The user tapped on the cancel button within the editor.
        return;
      }
    } catch (error) {
      // There was an error generating the video.
      print(error);
    }
    // highlight-events
  }
}
