# Sojorn Media Editor Migration - Implementation Summary

**Date:** January 24, 2026  
**Lead Developer:** Sojorn Team  
**Status:** ✅ Complete (Image Editor Fully Functional, Video Editor Prepared)

## Overview

Successfully migrated Sojorn's media editing suite to the Pro versions (`pro_image_editor` and `pro_video_editor`), standardized the implementation with unified result handling, aligned UI with AppTheme, and configured for temp directory storage with background upload integration.

---

## ✅ Completed Tasks

### 1. Dependency Management
- **Status:** ✅ Complete
- **Changes:**
  - Verified no redundant `video_editor` dependency exists (was already removed)
  - Retained `pro_image_editor: ^6.0.0`
  - Retained `pro_video_editor: ^1.2.3`
  - Added `ffmpeg_kit_flutter: ^6.0.3` for video processing support
  - All dependencies successfully fetched via `flutter pub get`

### 2. Unified Result Class
- **Status:** ✅ Complete
- **File:** `sojorn_app/lib/models/sojorn_media_result.dart`
- **Features:**
  - Handles both `Uint8List` bytes and `String` file paths
  - Factory constructors for image and video media types
  - Helper getters (`isImage`, `isVideo`, `hasBytes`, `hasFilePath`)
  - Web and mobile platform compatible

### 3. Image Editor Implementation
- **Status:** ✅ Complete - Fully Functional
- **File:** `sojorn_app/lib/screens/compose/image_editor_screen.dart`
- **Features:**
  - ✅ Uses `AppTheme.brightNavy` for primary actions, loading indicators, and active slider tracks
  - ✅ Uses `0xFF0B0B0B` (matte black) background matching design
  - ✅ Disabled distracting features:
    - Paint editor disabled
    - Text editor disabled
    - Emoji editor disabled
    - Sticker editor disabled
    - Blur editor disabled
  - ✅ Focus on high-quality editing: cropping, rotation, filters, and tune adjustments
  - ✅ Temp directory storage with `path_provider`
  - ✅ Returns `SojornMediaResult` with proper file paths or bytes
  - ✅ Custom AppBar with Undo/Redo and Save functionality
  - ✅ JPEG export at 85% quality

### 4. Video Editor Implementation
- **Status:** ⚠️ Prepared (Placeholder - FFmpeg Configuration Required)
- **File:** `sojorn_app/lib/screens/compose/video_editor_screen.dart`
- **Current State:**
  - Placeholder implementation that saves videos to temp directory
  - Properly structured with AppTheme branding
  - Returns `SojornMediaResult` for consistency
  - Configured for future Pro version integration
- **Required for Full Implementation:**
  - FFmpeg library integration and configuration
  - Platform-specific video codec setup
  - Video trimming, cropping, and rotation UI
  - Filter application for videos
- **Technical Specifications (Ready for Implementation):**
  - `generateInsideSeparateThread: true` for non-blocking exports
  - Export format: `.mp4` with H.264 codec
  - High-quality video output
  - Stickers and text overlays disabled per philosophy

### 5. Compose Screen Integration
- **Status:** ✅ Complete
- **File:** `sojorn_app/lib/screens/compose/compose_screen.dart`
- **Changes:**
  - Updated to use `SojornMediaResult` instead of `ImageEditorResult`
  - Properly handles both bytes and file paths
  - Background upload integration via `ImageUploadService`
  - Seamless web and mobile compatibility

## 🎨 Branding & UI Compliance

All editors strictly adhere to the Sojorn AppTheme:

| Element | Color | Usage |
|---------|-------|-------|
| **Primary Actions** | `AppTheme.brightNavy` (`0xFF1974D1`) | Buttons, active states |
| **Background** | Matte Black (`0xFF0B0B0B`) | Editor canvas background |
| **Panel Background** | Panel Black (`0xFF111111`) | Secondary panels |
| **Active Slider Track** | `AppTheme.brightNavy` | Slider active state |
| **Loading Indicators** | `AppTheme.brightNavy` | Progress spinners |
| **Text** | White (`0xFFFFFFFF`) | Primary text and icons |

---

## 📁 File Storage Architecture

### Temp Directory Strategy
- **Implementation:** Uses `path_provider.getTemporaryDirectory()`
- **File Naming:** `sojorn_image_[timestamp].jpg` and `sojorn_video_[timestamp].mp4`
- **Benefits:**
  - Automatic OS cleanup
  - No permission requirements
  - Cross-platform compatibility
  - Clean separation from user files

### Upload Integration
- **Service:** `ImageUploadService` (also handles videos)
- **Flow:**
  1. User edits media in editor
  2. Editor saves to temp directory
  3. Returns `SojornMediaResult` with file path/bytes
  4. Compose screen triggers upload via `ImageUploadService`
  5. Upload service sanitizes and uploads to Cloudflare R2
  6. Public URL returned and attached to post
