Problem

FlutterOptions.flutter_element_wait_timeout and FlutterOptions.flutter_server_launch_timeout are annotated -> timedelta | None, and their docstrings say they return a timedelta. Their setters accept a timedelta and store it as milliseconds. The getters, however, returned the raw capability value:

options = FlutterOptions()
options.flutter_element_wait_timeout = timedelta(seconds=10)
options.flutter_element_wait_timeout  # 10000, expected timedelta(seconds=10)

Every other millisecond timeout option, such as adb_exec_timeout and wda_launch_timeout, converts the stored value back to a timedelta.

Fix

Return timedelta(milliseconds=value) from both getters, or None when the capability is not set, matching the other timeout options. What gets sent to the server does not change.

Tests

• Added a unit test that sets one option as a timedelta and the other as an int, reads both back as timedelta, and checks that the capabilities sent are still in milliseconds. It fails without the fix with assert 10000 == datetime.timedelta(seconds=10).
• ruff check, ruff format --check, mypy appium and the full unit test suite pass.
