Deserialization

PhotoEditor 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 PESDK.openEditor method as the serialization parameter.


import 'dart:convert';

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

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

      // Open the photo editor and handle the export as well as any occurring errors.
      final result = await PESDK.openEditor(
          image: "assets/LA.jpg", serialization: serialization);

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