This cleans up several places where instead of allocating a std::unique_ptr immediately, we were making allocations with the new operator, then later wrapping in a unique_ptr. The previous code was correct but there was no reason not to allocate a unique_ptr immediately. This code makes no semantic changes; just applies a stylistic improvement that makes the code very slightly safer. ## Pre-launch Checklist - [X] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [X] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [X] I read and followed the [Flutter Style Guide] and the [C++, Objective-C, Java style guides]. - [ ] I listed at least one issue that this PR fixes in the description above. - [X] I added new tests to check the change I am making or feature I am adding, or the PR is [test-exempt].
