image url

I have a flutter project using flutter_echarts.
I want to add icons to my yAxis, using rich text. the icons are in assets/images/imageName.png,
but when I use it like this in 'rich'

backgroundColor: {
                           image: './assets/images/imageName.png'
                           },
                      },

or like this

backgroundColor: {
                           image: 'assets/images/imageName.png'
                           },
                      },

the icon is not displayed.
is there another way?

Because this lib abstract web assets to strings, you could not directly handle imge files.
The solution is to use Data URL , Echarts image property allows all legal URL forms, so just transform your image asset to a Base64 Data URL string just like we often do in CSS.
If you are not familiar with CSS Base64 Data URL, please search for docs like: https://stackoverflow.com/questions/17090571/is-there-a-way-to-set-background-image-as-a-base64-encoded-image
