It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging.

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group.

Code Review

This pull request updates the espresso package to use Java 17. This is achieved by updating the sourceCompatibility and targetCompatibility in android/build.gradle, and increasing the minimum required Flutter version to 3.35.0 and Dart SDK to ^3.9.0 in pubspec.yaml. The CHANGELOG.md and pubspec.yaml are updated to version 0.4.0+15.

While the changes are functionally correct for the package itself, I have a couple of points for consideration. According to the pub versioning philosophy, increasing the minimum Flutter version is a breaking change, which for a pre-1.0.0 package suggests a minor version bump to 0.5.0 rather than a build number increment. I've left specific comments on this in the relevant files. Additionally, the pubspec.yaml for the example app has not been updated with the new SDK constraints, which may cause it to fail and should be updated to match the package's new requirements.

According to the pub versioning philosophy, increasing the minimum Flutter SDK version is a breaking change.¹ For a package with a version less than 1.0.0, this should be a minor version bump. Please update the version to 0.5.0.
