How to upgrade to Polymer and PaperElements 1.0 using pubspec.yaml
I found a migration guide ( https://www.polymer-project.org/1.0/docs/migration.html ). My Dart project is not using chat, but pubspec.yaml, and when I changed the dependency version for PaperElements I get the message:paper_elements has no versions that match >=1.0.0
environment:
sdk: '>=0.8.10+6 <2.0.0'

browser: '>=0.10.0+2'
code_transformers: any
core_elements: '>=0.6.0'
dnd: any
logging: '>=0.9.3'
paper_elements: '>=1.0.0'

entry_points:

There are no elements for Dart yet. This is a work in progress and before they are published it is not possible to use them the way you did before. You can use Polymer.js elements in the meantime, of course, but then you have to use gazebo and dart-js-interop.
