apple_intelligence 0.2.0

Apple Intelligence for Flutter: on-device image generation streamed as it is made, plus a native text field with Writing Tools and Genmoji.

0.2.0

Writing Tools and Genmoji, via a real system text view.

• AppleIntelligenceTextField hosts a genuine UITextView/NSTextView inside Flutter, which is what makes Apple's text features work at all: Writing Tools attaches to a UIView and Genmoji is a property of UITextInput, and a Flutter text field is neither as far as the system is concerned.
• NativeTextController reads and writes the contents, and capabilities() asks the live view what it was actually granted rather than inferring it from the OS version.
• onChanged fires when the native view edits itself — which is the only way to notice that Writing Tools rewrote your text or a Genmoji was inserted.

This is deliberately not a drop-in for Flutter's TextField. It is a platform view, so it composites differently and costs more; styling does not inherit from your theme; and it exists on iOS and macOS only, rendering fallback elsewhere. The README says so before it says anything else about it.

Verified on macOS: the hosted view reports writingTools: true, genmoji: true, and text round-trips through the controller.

0.1.0

Initial release: Apple Intelligence image generation for Flutter.

• ImageCreator.generate produces images on device with no UI, delivered as a Stream so the first can be shown while the rest are still being made. Cancelling the subscription cancels the work on the device.
• ImagePlaygroundSheet.present shows Apple's own generation UI and returns the file it wrote, or null if the user cancelled.
• ImageCreator.availability reports the sheet and streaming separately, because the sheet is iOS 18.1 and streaming is 18.4 — a device can offer one and not the other.
• ImageConcept.text names a subject; ImageConcept.extractedFrom asks the system to find the subjects in a passage.
• Errors arrive as a typed hierarchy — OsTooOldException, GenerationUnavailableException, GenerationRefusedException with a specific reason — never as a bare PlatformException.

Verified against real Apple Intelligence hardware: two PNGs of about 4 MB, the first at 6.8s and the second at 10.3s.

Not included: Writing Tools and Genmoji. Both are planned; Writing Tools attaches to a native text view while Flutter renders its own text, so it needs a design decision rather than a wrapper.
