Catch-all commit for outstanding pre-existing local changes. Mixes several themes that would normally be split: - Rename: UxPlugin → XPlugin across iOS, macOS, Android registrants. - New top-level packages under lib/src/: anim/ (animated values, panes, sheets, dock, measured), core/ (Emitter, ReactiveBuilder scaffolding, presenter/widget/value/dispose primitives), navi/ (Screen/ScreenStack/Router/hero/transitions), reactive/. - Edits across existing plugins (clipboard, crash, file, gallery, keyboard, scanner, sensor, url) to align with the new core. - Test updates and CHANGELOG/README touches accompanying the above.

// Native data detection for XUrl. Synchronous, callable via dart:ffi.
|
|
//
|
|
// Exports two symbols:
|
|
// uint8_t* ux_match_url(const uint16_t* utf16, int32_t len, int32_t* out_size);
|
|
// void ux_free(uint8_t* buf);
|
|
//
|
|
// Output buffer layout (little-endian on Apple ARM64 / x86_64):
|
|
// u32 count
|
|
// count * { i32 start, i32 end, u32 kind, u32 url_len, u8[url_len] url_utf8 }
|
|
// where kind ∈ { 0=web, 1=email, 2=phone }.
|
|
//
|
|
// Backed by NSDataDetector (.link | .phoneNumber). The detector itself
|
|
// won't flag bare domains like `google.com` (Apple's stock apps make
|
|
// the same trade-off), so we run a second pass with a tight regex that
|
|
// requires a `/` or `?` after the domain — that pulls in `example.com/path`
|
|
// without dragging in `etc.` / `v1.2.3` / `Mr.Smith` false positives.
