flutter_image_clip 0.9.2

A reusable Android and iOS Flutter image clipping library with a ready-to-use crop editor UI and image processing APIs.

0.9.2

• 调整裁剪元数据恢复策略：ImageClipResult.region 现在会保存裁剪框映射到原图坐标后的虚拟矩形，允许 x / y 为负数或 width / height 超出图片边界，用同一组 rotationDegrees + x/y/w/h 即可恢复 Fit 模式下的左右或上下留白。
• 保存导出时会在内部把虚拟矩形夹到有效源图像素区域，不要求接入方额外传 visibleRegion 或 aspectRatio。

0.9.1

• 修复 Fit 模式下图片左右或上下留白时，保存后再传入初始裁剪信息会恢复成无留白位置的问题。
• 新增 ImageClipResult.visibleRegion 和 ImageClipResult.aspectRatio，用于持久化并恢复编辑器里的可见区域与裁剪比例。
• ImageClipEditor.initialAspectRatio 现在会优先于 initialCropRegion 的自动比例推导，方便业务按保存时的比例恢复 Position。
• README 改为英文优先的中英文文档，并缩小示例图为一行两张。

0.9.0

• 新增 ImageClipEditor.initialImagePath、showImageClipEditor(imagePath:) 和 ImageClipEditorController.loadImageFile()，相册本地文件可走 file-backed preview/save 链路，减少 UI isolate 原图 bytes 占用。
• ImageClipPlatformDecodeAdapter 支持从本地文件路径触发 Android/iOS 平台采样解码，示例首页选择相册后优先保留文件路径，只有路径不可用时才退回 readAsBytes()。
• ImageProcessor.probeFile 改为只读取文件头做格式探测，避免为了元数据把大图完整读入 UI isolate。
• 平台采样预览会在无透明通道时返回 JPEG、有透明通道时返回 PNG，减少照片预览的通道传输字节数。
• showImageClipEditor 默认启用 ImageClipPlatformDecodeAdapter，fullscreen 入口保持少参数也能使用平台 HEIC/HEIF 和 sampled decode 能力。
• 新增可选的 ImageClipFileProcessingAdapter 能力，内置平台适配器可对支持的本地文件 JPEG 裁剪保存走原生 cropFile，不支持或 PNG 输出时自动回退 Dart isolate。
• 示例首页新增 Pick/probe、Preview task、Save task 耗时指标，方便直接观察相册选择、预览和保存阶段的性能。
• 修正预览图缩小后映射回原图的保存区域，避免 10:16 等比例因独立 round 宽高而产生像素比例误差。
• 按 Figma 设计稿更新编辑器 Fit、Fill 和 Rotate 工具图标。

0.8.1

• 初始裁剪区域恢复时不再插入临时比例，会在支持的 aspectRatios 中选择精确或最接近的比例。

0.8.0

• 支持通过初始旋转角度和原图裁剪坐标恢复编辑器 Position。
• 传入初始裁剪坐标时，编辑器会根据宽高自动选中或插入对应比例。
• 新增 ImageClipAspectRatio.fromDimensions 与 ImageClipAspectRatio.fromCropRegion，方便业务侧复用比例推导规则。
• 新增 CropRegion.hasPositiveSize 与 CropRegion.clampToBounds，统一裁剪坐标边界处理。
• 新增 ImageClipResult.sourceRegion 和 ImageClipResult.transform，明确保存结果里的坐标系和变换元数据。
• ImageClipTaskProgress 增加完成状态 helper、相等比较和稳定的 fraction 夹取逻辑。
• 补齐 CropSettings 与 ColorAdjustment 的 map、copy 和相等比较 helper。
• 编辑器会忽略非正宽高的 initialCropRegion，越界坐标会在图片加载后夹到原图范围内。
• 输出、解码和处理设置从 map 读取时会清理非正数或越界值。
• 示例首页新增完整参数面板，fullscreen 入口保留最少参数。

0.7.4

• 改用 pub.dev README 会稳定渲染的 Markdown 图片语法展示两张截图。
• 进一步压缩发布截图到 360x800，减小页面展示尺寸和下载体积。

0.7.3

• 将发布截图替换为更小的 WebP 资源，降低 README 和 pub.dev 图片加载体积。
• README 预览区同时展示全屏编辑器和嵌入式示例两张截图。

0.7.2

• Move the iOS plugin source into the Swift Package Manager layout while keeping CocoaPods support.
• Run Android and iOS native decode work on background queues before returning MethodChannel results.
• Add the missing ImageClipEditorController constructor dartdoc.
• Document real-device release validation and repository security hardening tasks.
• Add pub.dev screenshots for the fullscreen editor and embedded example lab.

0.7.1

• Fixed release-check golden flakiness on remote Linux / Flutter stable by allowing a 1% pixel tolerance while keeping layout and semantics tests as stronger guards.
• Added a gated Publish to pub.dev job to the release workflow. Tagged packages publish through pub.dev GitHub Actions OIDC only after validation passes and PUB_DEV_AUTOMATED_PUBLISHING is enabled.
• Added process RSS delta tracking to the benchmark baseline to catch large-image memory regressions.
• Added a public API dartdoc check so new public APIs cannot be added without documentation.
• Added Dependabot, Dependency Review, issue forms, a pull request template, and SECURITY.md.
• Added release, troubleshooting, migration, and real-device validation guides.

0.7.0

• Moved Android integration tests into example/integration_test so generated root app scaffolding no longer interferes with plugin compilation.
• Moved the integration test dependency into the example app and removed it from the root package.
• Removed the bundled Inter font from the editor. The editor now inherits the host app font, reducing package size and style intrusion.
• Updated compatibility constraints to Dart >=3.10.0 <4.0.0 and Flutter >=3.38.1.
• Added CI coverage for both the minimum supported Flutter version and the latest stable Flutter version.
• Added iOS simulator integration tests. Android and iOS integration tests both cover the editor flow and native sampled decode.
• Mapped ImageClipPlatformDecodeAdapter platform errors to ImageClipUnsupportedFormatException, ImageClipPlatformException, or ImageClipDecodeException.
• Preserved original source dimensions in Android native sampled decode so preview crop coordinates map back to the source image reliably.
• Added layout tokens to ImageClipEditorTheme for the top bar, bottom bar, save button, and aspect-ratio controls.
• Added the iOS PrivacyInfo.xcprivacy manifest.
• Tightened .pubignore so test, benchmark, tool, and generated integration scaffolding files are not published.
• Added integration recipes, a platform matrix, and an accessibility checklist.
• Reworked the public API snapshot to use analyzer-based exported API discovery.
• Added command-level and test-level timeouts to Android integration tests with clearer timeout failures.
• Expanded README compatibility and public import guidance.

0.6.6

• Converted the package into an Android/iOS Flutter plugin with the built-in ImageClipPlatformDecodeAdapter.
• Added platform-side sampled decode and format normalization entry points for HEIC/HEIF and other system-supported image formats.
• Added ImageProcessor.probeFile, decodeFile, processFile, and writeImageToFile. File input is read inside the worker isolate to reduce UI-isolate byte copying.
• Added Android emulator integration tests for loading, preview thumbnails, rotation, flipping, saving, and Chinese labels.
• Added JPEG preview decode and file-path crop/export cases to the benchmark suite.
• Added tool/check_api_snapshot.dart and tool/api_snapshot.json to guard key public APIs in CI.
• Split the editor save flow into editor_save.dart to reduce the maintenance load in editor.dart.
• Added ImageClipEditorLabels.english and ImageClipEditorLabels.zhHans.
• Added tag-triggered release checks that run format, analysis, tests, benchmarks, API docs, and pub dry-run before publishing.

0.6.5

• Added ImageClipDecodeSettings for preview decode target long-side configuration.
• Added sourceWidth and sourceHeight metadata to EditedImage.
• Added ImageProcessor.decodePreviewBytes and decodePreviewBytesTask.
• Added ImageClipDecodeAdapter so callers can normalize platform-only formats or run platform sampled decode before Dart decoding.
• Added ImageClipEditor.previewDecodeSettings. The editor can use a smaller preview image while saving still maps the crop region back to original source bytes.
• Added map, copy, and equality helpers to ImageClipResult, CropRegion, and core settings models.
• Added benchmark regression checking through --check benchmark/baseline.json.
• Added Android debug APK and iOS no-codesign debug builds to CI.
• Added tests for preview-to-source export, large text landscape layout, decode adapters, and model stability.

0.6.4

• Changed editor rotate and flip actions to update preview state immediately. The final save maps the preview crop area back to source pixels and exports once.
• Added ImageClipCropTransform and ImageClipDimensions for reusable rotation/flip crop coordinate mapping.
• Added previewRegion, flippedHorizontally, and flippedVertically metadata to ImageClipResult.
• Added outputSettings support to ImageProcessor.rotate, rotateRight, flipHorizontal, flipVertical, and their task APIs.

• Added HEIC/HEIF header detection and typed ImageClipUnsupportedFormatException failures before pure Dart decoding.
• Added ImageClipDecodedSession for keeping decoded pixels in memory across multiple small-image operations.
• Added Semantics for the editor preview, crop frame, tool buttons, and aspect-ratio controls.
• Added a default editor golden test for visual regression coverage.

• Added session-level task cancellation.
• Organized the example as a standalone Flutter app with its own example/pubspec.yaml.
• Added mobile image fixture tests for EXIF orientation values 1-8, transparent PNG, and corrupt JPEG input.

0.6.1

• Added ImageProcessor.probeBytes and ImageClipImageInfo for detecting PNG, JPEG, GIF, and WebP format and dimensions before full decoding.
• Added header-based input pixel limit checks before decode to reduce memory pressure from oversized images.
• Switched large isolate byte messages to TransferableTypedData.
• Added timeout support to ImageClipTask.fromFuture.
• Added ImageClipEditor.onProgress and wired editor progress UI to background task progress.
• Updated the example with gallery selection, sample loading, task cancellation, input probe details, and export preview.
• Added --json output to the benchmark command.

0.6.0

• Limited published platform support to Android and iOS.
• Updated README and pubspec descriptions to remove desktop and web support implications.
• Split editor UI code into controller, editor, preview panel, toolbar, result page, theme, labels, and painter files.
• Added ImageClipTask, ImageClipTaskOptions, and ImageClipTaskProgress for cancellation, progress, and timeouts.
• Added ImageClipEditorController.cancelTask().
• Added benchmark/image_processor_benchmark.dart covering decode, rotate/crop/JPEG export, and large-image downscale cases.
• Added tests for task progress and cancellation.

0.5.0

• Added ImageClipPipeline and ImageClipPipelineStep for batching decode, rotate, crop, flip, resize, color adjustment, and export into one background task.
• Added ImageProcessor.processPipeline and processBytes to reduce repeated decode/encode work.
• Refactored image processing into dedicated exception, model, pipeline, isolate job, pixel operation, and sample image modules.
• Kept existing single-step APIs such as cropRegion, rotate, adjustColor, and exportJpeg.
• Added pipeline tests for raw byte input and existing EditedImage input.

0.4.0

• Added ImageClipEditorController for loading images, clearing images, resetting the crop viewport, rotating images, reading the crop region, and triggering crop operations from parent widgets.
• Improved editor async lifecycle handling so newer image load requests invalidate older task results.
• Added stale-result protection to crop saving when the current image is replaced while a save is still running.
• Added widget tests for controller-driven flows and out-of-order async image loading.
• Updated README controller integration examples.

0.3.0

• Added ImageClipEditorTheme for configurable editor and result page colors, borders, crop overlays, and framed surface radius.
• Added EXIF orientation baking during image decoding so rotated camera photos crop with the expected dimensions.
• Added ImageClipProcessingSettings for input pixel limits, output pixel limits, and automatic downscaling.
• Added typed exceptions for decode failures, processing failures, invalid crop regions, and oversized images.
• Improved configurable crop ratio presets so custom ratio frames inherit editor theme tokens.
• Added GitHub Actions CI for formatting, analysis, tests, API docs, and pub dry-run validation.
