我正在从URL加载我的圈子头像的图像，并且显示以下错误：
[VERBOSE-2:codec.cc(97)] Failed decoding image. Data is either invalid, or it is encoded using an unsupported format.
flutter: ══╡ EXCEPTION CAUGHT BY IMAGE RESOURCE SERVICE ╞════════════════════════════════════════════════════
flutter: The following _Exception was thrown resolving an image codec:
flutter: Exception: operation failed
这是我的代码：
CircleAvatar(
backgroundColor: blueColor,
radius: 45,
child: new Text( strFName.substring(0, 1) + strLName.substring(0, 1) style: styleCircleName,),
backgroundImage: NetworkImage(strImageURL),
)
