The following assertion was thrown resolving a single-frame image stream:
Unable to load asset: "/data/user/0/com.example.example/cache/libCachedImageData/5d7b41a0-2869-11ee-8a7c-19fa185feb9e.svg".

Because flutter_svg_provider 0.1.6 depends on flutter_svg ^0.18.0 and no versions of flutter_svg_provider match >0.1.6 <0.2.0, flutter_svg_provider ^0.1.6 requires flutter_svg ^0.18.0.
So, because xxx depends on both flutter_svg ^0.19.1 and flutter_svg_provider ^0.1.6, version solving failed.

The <style> element is not implemented in this library.

Style elements are not supported by this library and the requested SVG may not render as intended.
If possible, ensure the SVG uses inline styles and/or attributes (which are supported), or use a
preprocessing utility such as svgcleaner to inline the styles for you.
