by id
and provided transformations
if any
Uses NetworkImage to fetch image from Uploadcare CDN
Example:
Image(
image: UploadcareImageProvider(
_fileInfo.id,
transformations: [
BlurTransformation(50),
GrayscaleTransformation(),
InvertTransformation(),
ImageResizeTransformation(Size.square(58))
],
),
// ... other Image params
)
