Flutter base64与图片

什么是Base64

廖雪峰的博客

1. 图片转base64

ImagePicker.pickImage(source: ImageSource.gallery).then((value)async{
    
    
	List bytes =await value.readAsBytes();
	String bs64 = base64Encode(bytes);
	String bs64Image ="data:image/png;base64,"+bs64;
	print(bs64Image);
});

2. base64显示为图片

str= str.split(',')[1];
Uint8List bytes = Base64Decoder().convert(str);

Image.memory(bytes)
