Flutter tests can hang indefinitely when pumpAndSettle() is called without a timeout argument. The MCP server was waiting on the process forever with no way to recover. Adds a timeout_seconds parameter (default 120) to the test tool. When the timeout fires, sends SIGKILL to flutter_tester via pkill — the only reliable mechanism to terminate a hung Flutter test process — then returns an actionable error to the caller.

Hey @eliasreis54, this might fix the MCP issue where timeouts from flutter test aren't bubbled up. But since the same issue exists in the very_good test command itself, shouldn't the fix be applied there too?
There we might find better way to tackle this, because this might introduce many issues (120 seconds for large codebases is quite aggresive)
Adds a --timeout <seconds> option to very_good test. When set, a Timer fires pkill -KILL -f flutter_tester and completes the test run with a non-zero exit code. No timeout is applied when the flag is omitted. The MCP server's own .timeout() + pkill block is removed in favour of passing --timeout directly to the CLI, keeping the kill logic in one place.

Description
Flutter tests can hang indefinitely when pumpAndSettle() is called without a timeout argument. The MCP server was waiting on the process forever with no way to recover.
Adds a timeout_seconds parameter (default 120) to the test tool. When the timeout fires, sends SIGKILL to flutter_tester via pkill — the only reliable mechanism to terminate a hung Flutter test process — then returns an actionable error to the caller.
