flutter 将组件转换成图片

## 使用
1. 导包
```
import 'package:widget_to_image/WidgetToImage.dart';
```
2. 使用
```
GlobalKey globalKey = GlobalKey();

WidgetToImage(
  globalKeys: globalKey,
  alignment: Alignment.center, 
  imageStr: "我是水印文本",
  imagePath: "images/shouji_bj2.png",
  stringSize: 16.0,
  stringColor: Colors.blue,
  // 需要保存下来的组件 可以是任意组件，child 为空时 imagePath 不可为空
  child: QrImage(
    data: "${logic.myInvitationsEntity?.data?.shareUrl ?? ''}",
    version: QrVersions.auto, 
    size: 185,
  ),
),


// 拿到widget转换后的图片
// 返回 getByte64，getFile，getUint8List 三种
Future<File> file = getWidgetToImage.getInstance(globalKey1).getFile();
file.then((value) => {
   print(value)
});
