filmkit 0.7.1

Photo and video editing for Flutter: native export, LUT filters and an Instagram-style editor.

0.7.1

• Example: picks with filmkit_picker instead of insta_assets_picker. The app no longer needs the workarounds for insta_assets_crop (a raised compileSdk, CocoaPods on iOS). The README points to filmkit_picker.

0.7.0

• CropView is public: the crop tool's pan and pinch-zoom over any child, for a crop preview outside the editor (a picker). showGrid: hides the grid while it stays interactive.
• FilmkitEditor.open(title:) / FilmkitEditorPage.title: a title in the app bar, e.g. "2/4" when editing several files in a row.
• EditorOptions.copyWith and EditorTexts.copyWith.

0.6.2

• Editor: pinch-to-zoom in the crop tool follows the fingers. When both fingers moved in the same frame, the second update started from the state before the first one: the zoom lagged and the image drifted sideways.
• Widget tests for the editor screen, the crop view, the trim bar and LutFilter (with fake native code and video player), and a CI on GitHub Actions.

0.6.1

• Android: getVideoFrame falls back to the closest key frame when the exact frame times out (4K 10-bit HDR videos on a Pixel 8a), instead of failing. Later frames of that file go straight to key frames.
• Editor: a video whose thumbnails fail still opens (without thumbnails). Before, 4K HDR videos showed "Can't open this file" on Android.

0.6.0

• CropState.fromRect: a crop state from a normalized rect, e.g. the area chosen in a picker.
• Example: pick with insta_assets_picker, then edit with filmkit (the picker's ratio and area become the editor's initial crop). See the README.

0.5.0

• Re-editing: EditorResult.state (EditorState: look, intensity, adjustments, crop ratio / zoom / position, trim), serializable to JSON, and FilmkitEditor.open(initialState:) to reopen the editor where the user left off.
• EditorResult.lookIntensity, adjustments and aspect now read from state.

0.4.0

• Instagram-style editor: FilmkitEditor.open(context, path:) with filters (10 built-in looks generated in Dart, or your own Looks / .cube files) and their intensity, adjustments (brightness, contrast, saturation, warmth, baked into the same LUT), crop with ratios, pan and zoom, and video trim with a thumbnail strip. Returns an EditorResult (the EditSpec, and the exported file unless EditorOptions.export is false). Labels configurable with EditorTexts.
• LutFilter keeps the previous table applied while a new one loads, and keeps its child's state when the filter is toggled.
• Depends on video_player for the video preview.

0.3.0

• Photo export: Filmkit.exportImage (JPEG, HEIC, PNG, WebP… in, JPEG out) with the same EditSpec as videos (crop in displayed coordinates, maxDimension, LUT). The EXIF orientation is applied to the pixels; capture date, camera and exposure metadata are kept, the location only with keepLocation. Android decodes only the cropped region at the needed resolution.

0.2.0

• LUT filters: CubeLut (.cube parsing and writing, intensity, CPU reference), EditSpec.lut / lutIntensity applied by the export (Media3 SingleColorLut, Core Image CIColorCubeWithColorSpace in CoreMedia's BT.709 space), and the LutFilter widget for the live preview (shader), which renders the same colors.
• Filmkit.getVideoFrame: a frame as displayed, optionally scaled down.

0.1.0

• Headless video export: Filmkit.exportVideo with an EditSpec (trim, crop in displayed coordinates, max output size), progress, cancellation and several exports at once. Media3 Transformer on Android, AVFoundation on iOS. Output: MP4, H.264 + AAC, SDR.
• HDR sources are tone mapped to SDR. On Android, OpenGL tone mapping falls back to MediaCodec, then to a hdrUnsupported error.
• Filmkit.getVideoInfo: displayed size, duration, audio and HDR flags.

0.0.1

• Project scaffold.
