@wendux 在php端使用$_FILES接收文件，还是只能接收到1个；

1：flutter 端原始参数如下：

上传文件参数：[File: '/storage/emulated/0/Customize/Wallpapers/387596.jpg', File: '/storage/emulated/0/Customize/Wallpapers/151296.jpg']

其它参数：{id: 2739, token: C6114DEE9236F025C92A20831312A697}

2：flutter dio端加入formdata原始代码如下：

FormData formData = new FormData();

//加入其它参数

if (data.length > 0) {

data.forEach((key, val) {

formData.add(key, val);

});

}

//加入图片

if (images.length > 0) {

var random = new math.Random();

List img = [];

for (int a = 0; a < images.length; a++) {

img.add(new UploadFileInfo(

images[a],

random.nextInt(10000).toString() +

'-' +

images[a].toString().substring(

images[a].toString().lastIndexOf('/') + 1,

images[a].toString().length - 1)));

}

formData.add("files", img);

}

Response response = await dio.post(url, data: formData);

return response;

3：提交数据时日志如下：

使用0.1.5版本，还是不行；
