- RouteGeometry (lib/domain/mission/route_geometry.dart): physically
grounded flight path - straight segments + tangential arcs at each
course change, sized from the drone's minimum turn radius (doc 3.7/4.6),
replacing a naive spline that would suggest unrealistic turn radii.
Marks a vertex "bad" (turn angle >= 160°, tangent length exceeding 90%
of either adjacent leg, or exceeding the waypoint's catch radius) and a
leg "bad" when the required climb/descent rate exceeds the drone's
max climb/descent rate. Pure Dart, no Flutter dependency, so it stays
usable if the mission domain is ever split into its own package (4.22).
Wind-based turn-radius correction from the prototype isn't ported yet -
the wind system (doc 3.8) doesn't exist in the Flutter app.
- MissionMap now draws each RouteSegment as its own Polyline, colored red
when bad instead of a single plain white line; waypoint markers turn red
too when their vertex is bad.
- ValueWheel: vertical drag-to-adjust tape control (HTML prototype's
#altWheel/#spdWheel), custom-painted tick marks, blue center indicator,
gradient fade at top/bottom. Wired into PlanScreen on both screen edges
with Alt/Speed readouts.
- curAlt/curSpeed now live in PlanScreen state instead of fixed constants:
dropping a new waypoint uses whatever the wheels are currently set to;
entering editing mode on an existing waypoint loads its values into the
wheels; adjusting a wheel while editing writes live into that waypoint
(provider gained setAltitude/setSpeed to match the existing
moveWaypoint/toggleAction pattern).
Added dedicated unit tests for the geometry (empty list, straight line,
feasible 90° turn producing a line-arc-line segment sequence, an
infeasible near-180° turn, and an infeasible descent rate) rather than
relying on eyeballing it on the emulator - this is exactly the kind of
ported-math correctness that's hard to verify visually but easy to get
subtly wrong. All 11 tests (previous 6 + these 5) and flutter analyze
pass. Also manually verified the wheels on the Pixel_10a emulator: drag
changes the value and the on-screen readout in real time.
