推荐答案

您可以使用图片2.1.12

您必须在dart文件中的库下面导入

You have to import below library in your dart file

import 'package:image/image.dart' as img;

捕获图像并在图像上绘制字符串的功能

Function for capture image and draw string on image

  Future<File> drawTextOnImage() async {
    var image = await ImagePicker.pickImage(source: ImageSource.camera);

    var decodeImg = img.decodeImage(image.readAsBytesSync());

    img.drawString(decodeImg, img.arial_48, 0, 0, DateTime.now().toString());

    var encodeImage = img.encodeJpg(decodeImg, quality: 100);

    var finalImage = File(image.path)..writeAsBytesSync(encodeImage);

    return finalImage;
  }
