403 when trying to fetch image from S3 with trailing spaces

I have the following URL: `https://s3.amazonaws.com/sscatalogo/softsite2qualidade/001.png ` (note the trailing space).

When I access this URL via Firefox, I got the image with no problem. When I access the URL via CURL, even with the trailing space, I still got the image with no problem. I put the trailing space inside the URL string like this:

curl -o a 'https://s3.amazonaws.com/sscatalogo/softsite2qualidade/001.png ' -v i

But, when I've tried to access this URL via `CachedNetworkImage`, I didn't got the image. It worked once I've `.trim()`ed the URL via dart.

Shouldn't Flutter Cached Network Image behave just like CURL?
