Hey, after i upgraded to flutter 1.17.0 my builds crashed all the time. The reason for this got fixed in the new flutter_svg version so i updated it for you :)

Sincerely kay4ik

Is it possible if I use illustration without internet connection? Because, you will send request to this https://42f2671d685f51e10fc6-b9fcecea3e50b3b59bdc28dead054ebc.ssl.cf5.rackcdn.com/illustrations/ right? I need it works well when offline :( I hope you can do it hehe Never mind, it's just my opinion

This PR mainly addresses #1

Changes

1. Add errorWidget: This widget will be displayed when the future completes with an error. The default is a Text with an error message.
2. Update the example to show a sample usage of errorWidget
3. Update example/pubspec.yaml to use a relative path of the package. This eliminates the need to update it with every release and allows to test the example app while developing and updating the package
4. Make getSvgString private since its only supposed to be used internally by the package and shouldn't be exposed as a public API
5. Use a constrained dependency for flutter_svg, which is the recommended way. This will increase the package's maintenance score to 100

Is your feature request related to a problem? Please describe. There is a need for administrators in my app to select one of the illustrations as part of a category Eg. The category is "Painting" and admin select UnDrawIllustration.making_art image from a grid view and the choice will be converted into a string like UnDrawIllustration.making_art.toString() and convert back to UnDrawIllustration.

Describe the solution you'd like Able to get a list of illustrations like List<UnDrawIllustration> and display it on a grid view. It'd be great too if it is possible to convert string to UnDrawIllustration like UnDrawIllustration.parse()

Describe alternatives you've considered Download all the svg and store them in Firestore

Compile gets failed after Using Undraw. Before that everything works perfectly

Very naive approach to add offline support for the package.

To use the offline mode:

• make sure to add the svg file downloaded from https://undraw.co/ to the assets folder
• set mode: 'offline' when instantiating UnDraw

Contributions/suggestions are appreciated! :smile:

It's not an issue. More of a question. How are the parameters sent in the request header of the CDN service used by this library for retrieving the images ? Foe example, how can I send the color or the height/width etc along with the name of the illustration ?
