Basic Usage

1. Sticker View (Text + Picture)

StickerEditingView(
  height: 300,
  width: 300,
  child: targetWidget,
  fonts: fonts,
  palletColor: colorPallet,
  assetList: stickerList,
  texts: texts, // Texts to be shown in the Sticker Editor
  pictures: pictures, // Pictures to be shown in the Sticker Editor
),

2. Text Editing Box

Container(
  height: 300,
  width: 300,
  color: Colors.blue,
  child: Stack(
    children: [
      TextEditingBox(
        fonts: fonts,
        boundHeight: 200,
        boundWidth: 100,
        isSelected: true,
        palletColor: colorPallet,
        newText: TextModel(
            name: 'Text EditingBox',
            textStyle:
                GoogleFonts.pacifico(fontSize: 25, color: Colwhite),
            top: top,
            isSelected: true,
            textAlign: TextAlign.center,
            scale: 1,
            left: left),
      ),
    ],
  ),
),

3. Picture Editing Box

Container(
  height: 300,
  width: 300,
  color: Colors.blue,
  child: Stack(
    children: [
      StickerEditingBox(
          boundHeight: 200,
          boundWidth: 200,
          pictureModel: PictureModel(
            isSelected: false,
            left: 50,
            top: 50,
            scale: 1,
            stringUrl: 'https://github.com/tinyjin/sticker_editor_plus/blob/main/example/assets/t-shirt.jpeg?raw=true',
          )),
    ],
  ),
)

4. Prevent User Interaction (view only mode)

Users will not be able to move, rotate, or resize stickers or text—they will only be able to view them.

This is useful in situations where you want to show a preview or a finalized image, such as when reviewing a design before saving or sharing, or when you want to prevent further editing by the user.

StickerEditingView(
  height: 300,
  width: 300,
  texts: texts,
  pictures: pictures,
  // ...
  viewOnly: true,
),

5. Sticker Data Serialization

Text (TextModel) and image (PictureModel) data used in the sticker editor can be serialized and deserialized to/from JSON format.
This feature allows you to save user-created designs, send them to a server, or reload them to continue editing.

5-1. TextModel/PictureModel Serialization

StickerEditingView(
  // Called when the user completes editing and presses the Save button
  onSave: (List<TextModel> editedTexts, List<PictureModel> editedPictures) async {
    // Serialize edited data to JSON
    await _saveDesignToStorage(editedTexts, editedPictures);
    
    Map<String, dynamic> designData = {
      'texts': texts.map((text) => text.toJson()).toList(),
      'pictures': pictures.map((picture) => picture.toJson()).toList(),
    };

    // Save to server or LocalStorage as needed
    print(designData);
  },
);

5-2. Text & Picture Restoration

Future<void> _loadSavedDesign() async {
   Map<String, dynamic> designData = jsonDecode(jsonString);

   // Loads TextModel
  List<TextModel> loadedTexts = [];
  if (designData['texts'] != null) {
    loadedTexts = (designData['texts'] as List)
        .map((data) => TextModel.fromJson(data))
        .toList();
  }

  // Loads PictureModel
  List<PictureModel> loadedPictures = [];
  if (designData['pictures'] != null) {
    loadedPictures = (designData['pictures'] as List)
        .map((data) => PictureModel.fromJson(data))
        .toList();
  }

  setState(() {
    texts = loadedTexts;
    pictures = loadedPictures;
  });
}

@override
Widget build(BuildContext context) {
return Scaffold(
  body: StickerEditingView(
    // ...
    texts: texts, // Restored Texts
    pictures: pictures, // Restored pictures
    onSave: (editedTexts, editedPictures) async {
      // ...
    },
  ),
);
}
