Some checks failed
CI / Windows build (push) Has been cancelled
Whole-project `flutter analyze` exited 1 on 17 pre-existing info/warning lints (no errors) in dev tools and test files. Clean them so analyze is green: - editor_repository_test: drop the redundant sqflite_common import; keep the used utils import with a transitive-dep ignore. - pen_* widget tests: `(_, __)` wildcard params -> `(_, _)`. - search_snippet_test / gen_bench_pdf / gen_dense_strokes: drop needless interpolation braces; remove an unused `Size` show and an unused local; mark the gen tool as print-allowed. No runtime behavior changed. flutter analyze: No issues found. Affected tests: 22/22 pass.
