This pr aims to complete #172188 by refactoring all files in
`packages/flutter/lib/src/material` to adopt Dart 3.8's null-aware
elements feature. Each file was refactored in its own commit for clear,
incremental changes and traceable history.

### Motivation

Following the
#172188 (comment),
this PR is intentionally scoped to a single folder to keep the review
surface manageable. Migrating package by package enables more focused
code review, easier troubleshooting, and a safer incremental adoption of
the new language feature.

### Approach

- **Scope:** Only files under `packages/flutter/lib/src/material` have
been refactored.
- **Commits:** Each file refactored in its own commit for granularity
and traceability.
- **Code style:** Changed list element conditionals to use null-aware
elements where applicable, improving readability and reducing verbosity.

### Testing

- All existing tests were run after each change.
- All tests passed except for `chip_test.dart`, which was already
failing before these changes and continues to fail after. No new test
failures were introduced by this PR.

### Additional Notes

- No functional or behavioral changes were made; this is a pure refactor
for code clarity and modernization.
- Adhering to the incremental migration strategy proposed in the
referenced issue for safer and more effective review.

fixes: #172259

The contents of the files (pom, .jar) produced by android also reference
the artifacts version number (which includes the git-hash). The flutter
recipies are just dumb re-uploaders for the content hash at the moment.
In order to change the contents, we can just update some GN files. This
has some local duplication of files, but is acceptible for now.

I've also added the content-hash as a string in the .so file and its
printed out next to the hash.

"Why is the folder name the git-hash?"

The recipies have a quirk - the logs will have you believe they upload
individual files such that "gsutil cp a.jar b.jar" would produce
"b.jar"; but that's not what's going on. The recipies recurisively
upload from the root of the temporary folder the files are copied to. At
the moment, the "Ensure" step of builder.py updates the URL path, so it
will handling uploading to the correct path, but not the file or its
contents (hence this change).

Plan for the future: at some point we can stop producing git-ref hashes.

E.g.
git-hash: dfd7318 content-hash:
3bfa6013b7be2b0bbadc22a9c3495d4efa46aba7

This PR adds support for customizing the `splashColor` in the
`ExpansionTile` widget.

Currently, ExpansionTile uses the theme’s default splash color without
allowing overrides.
This change introduces a new optional splashColor parameter so
developers can better control the ripple effect color when the tile is
tapped.
