-- [ ] Plan & identifikasi penyebab garis merah pada `evaporasi_chart_widget.dart`.
+## Step 1: Fix evaporasi.dart parse conflict
-- [ ] Periksa isi file `evaporasi_chart_widget.dart` untuk potensi error sintaks/typing.
+- Remove leftover git conflict markers in packages/monitoring_repository/lib/src/models/evaporasi.dart
-- [ ] Lakukan perbaikan kode sesuai penyebabnya.
+- Unify timestamp parsing logic into a single implementation
-- [x] Analisis file `evaporasi_chart_widget.dart` untuk potensi error sintaks/typing yang memicu garis merah.
+- Ensure `factory Evaporasi.fromJson` always returns a non-null `Evaporasi`
-- [x] Perbaiki penyebab garis merah pada `evaporasi_chart_widget.dart` (syntax/indentation/typing).
-- [ ] Jalankan `flutter format` dan `flutter analyze` (manual di terminal) untuk memastikan error hilang.
 
+## Step 2: Fix Google Sign-In import errors
+- Investigate why `package:google_sign_in/google_sign_in.dart` is reported missing
+- Update user_repository dependency versions if needed
+- Run `flutter pub get` (from c:/flutter/klimatologi) and `flutter analyze` again
+
+## Step 3: Re-run analyze and address remaining warnings
+- Run `flutter analyze` and fix any remaining compile errors
+- Optionally clean up performance/deprecation warnings (const constructors, withOpacity deprecation, Share->SharePlus)

+# Edit plan (approved before edits)
+
+## Information gathered
+- `flutter analyze` reports many issues, but the compile-stopping ones are:
+  1) `packages/monitoring_repository/lib/src/models/evaporasi.dart` contains unresolved git merge conflict markers (`<<<<<<< HEAD`, `=======`, `>>>>>>> ...`) and thus causes syntax errors and incorrect factory return type/assignments.
+  2) `packages/user_repository/lib/src/firebase_user_repo.dart` cannot resolve `package:google_sign_in/google_sign_in.dart` and related symbols (`GoogleSignIn`, `GoogleSignInAuthentication`).
+- Read `evaporasi.dart`: conflict markers exist inside `Evaporasi.fromJson`, causing broken code.
+- Read `firebase_user_repo.dart`: it imports `package:google_sign_in/google_sign_in.dart` and uses `GoogleSignIn`, `GoogleSignInAuthentication`.
+- Read `packages/monitoring_repository/pubspec.yaml`: no `google_sign_in` dependency there (likely only in user_repository).
+- Read `packages/user_repository/pubspec.yaml`: `google_sign_in: ^6.3.0` is present.
+- `search_files` for conflict markers returned none (likely because pattern needs exact marker search or repo search mismatch), but reading the file shows markers are present.
+
+## Plan
+### Step A — Fix evaporasi.dart merge conflict
+- Edit `packages/monitoring_repository/lib/src/models/evaporasi.dart`:
+  - Remove all `<<<<<<< HEAD`, `=======`, `>>>>>>> ...` markers.
+  - Consolidate timestamp parsing:
+    - Keep a robust `parseTimestamp(dynamic raw)` helper.
+    - Use one `rawTimestamp` priority order: `json['timestamp'] ?? json['time'] ?? json['datetime']`.
+    - Keep legacy fallback from `json['waktu']` (HH:mm:ss) if other timestamp fields are missing.
+  - Keep filtering for evaporasi (0..50) and tinggiAir (0..100) and sensor sanity for suhu (-50..100).
+  - Ensure `factory Evaporasi.fromJson(...)` always returns an `Evaporasi` with a non-null `timestamp`.
+
+### Step B — Fix google_sign_in missing import/class errors
+Because `google_sign_in` is declared but analyzer can't find the Dart library:
+- Check whether the dependency actually downloaded/available. The simplest fix path is:
+  - Run `flutter pub get` correctly (Windows shell issue is present: `&&` is not valid in the terminal context).
+  - Re-run `flutter analyze` to see if the missing import resolves.
+- If still failing:
+  - Inspect `packages/user_repository/pubspec.lock` / ensure plugin supports current platform (and that the package name/dart import matches).
+  - Update `google_sign_in` version to a compatible one if necessary.
+
+### Step C — Re-run analyze
+- After Step A and Step B, run `flutter analyze` again and fix any remaining compile errors.
+
+## Dependent files to edit
+- `packages/monitoring_repository/lib/src/models/evaporasi.dart`
+- Potentially `packages/user_repository/pubspec.yaml` (only if dependency resolution still fails)
+
+## Followup steps
+- Run `flutter pub get` (from `c:/flutter/klimatologi`).
+- Run `flutter analyze` again.
+- If compile succeeds, optionally address warnings (prefer_const_constructors, deprecated withOpacity, Share -> SharePlus, etc.).
+
+<ask_followup_question>
+Approve Step A (remove merge conflict and fix timestamp parsing in evaporasi.dart). After that I will proceed to Step B (google_sign_in resolution) based on the next analyze output.
