☂️ Removal & Clean up: Deprecate and remove old design libraries from the SDK #172942
Description
This issue tracks the long-term work for removal, the final step in the design system decoupling project (#101479).
After a long and well-communicated deprecation period , this final phase involves completely removing the original material and cupertino libraries from the core Flutter SDK. This will finalize our transition to a leaner, more modular framework and update the broader ecosystem to reflect this new architecture.
This phase also enables us to explore new opportunities for an improved developer experience.
This is a long-term project, and the sub-issues will track the following major areas of work:
- Final Removal: The breaking change to remove the deprecated libraries from the SDK.
- Ecosystem Updates: Updating dependencies like performance benchmarks, as well as official documentation, samples, codelabs, and tutorials to use the new packages.
- Reinvent the Counter App: Exploring a new vision for the default application created by flutter create.
- "Bring Your Own Design Language": Investigating support in the flutter tool for custom templates, allowing developers to choose a design system at project creation.
The above will likely become sub issues for tackling in the future. The reinforcement and relocation work will need to be tackled first though.
