From fab6aa504fc36c0dbac9f9128c14682bd78d781d Mon Sep 17 00:00:00 2001 From: Richard Brown Date: Fri, 24 Apr 2026 17:36:44 +0100 Subject: [PATCH 1/5] fix(wear): cache user doc stream to avoid re-subscribe on rebuild _userDocStream() was invoked directly inside build(), so each rebuild created a new Firestore snapshot subscription. This caused unnecessary reads and a brief "0 pts / 0 claimed" flicker every time the sibling StreamBuilder emitted (e.g. streak change). Cached in a late final field to match the existing _streakStream pattern.
