image_painter 0.7.0

A flutter package for drawing over images. Supports color, strokeWidth, different paintModes and exporting image.

0.7.0

Breaking Changes

• Controller is exposed out of library. As a result of exposing, it has been renamed to ImagePainterController in order to avoid conflict with other Controller name objects.
• width and height parameters are now required for ImagePainter.Signature() constructor.
• GlobalKey is no longer required to extract the image. It can be done through the ImagePainterController instance now.

/// Previously:

final _imageKey = GlobalKey<ImagePainterState>();
/// Provide key to the painter.
ImagePainter.network("https://sample_image.png",
                  key: _imageKey,scalable: true),

/// Export the image:
Uint8List byteArray = await _imageKey.currentState.exportImage();
/// Now you use `Uint8List` data and convert it to file.
File imgFile = new File('directoryPath/fileName.png');
imgFile.writeAsBytesSync(image);

/// Current:

final imagePainterController = ImagePainterController();

/// Provide controller to the painter.
ImagePainter.network("https://sample_image.png",
                  controller: imagePainterController,scalable: true),

///Export the image:
Uint8List byteArray = await imagePainterController.exportImage();
//Now you use `Uint8List` data and convert it to file.
File imgFile = new File('directoryPath/fileName.png');
imgFile.writeAsBytesSync(image);

• Parameters initialPaintMode, initialStrokeWidth, initialColor has been removed. They can be set while initializing the controller.

final ipController = ImagePainterController(
    color: Colors.green,
    strokeWidth: 4,
    mode: PaintMode.line,
);
