flutter_pdfview 1.5.0-beta.7

flutter_pdfview: ^1.5.0-beta.7 copied to clipboard

• Improve Android/iOS render quality defaults for #158 (#357): density-aware page-part cache, apply Dart’s thumbnailRatio 0.8 when the param is omitted (AndroidPdfViewer’s static default is 0.3), keep useBestQuality / enableAntialiasing / enableRenderDuringScale true when params are missing, pin iOS contentScaleFactor to the screen scale, and document quality knobs + hard Pdfium limits in the README
• Includes everything in 1.5.0-beta.6

• Fix #175: getScreenshot no longer returns a white image under hybrid composition. Android captures via PixelCopy (with a software-layer View.draw fallback); iOS rasterizes the PDFKit layer and falls back to drawing the current PDFPage (drawing-cache / hierarchy snapshots are avoided on both platforms) (#356)
• Includes everything in 1.5.0-beta.5

• Fix load flash / first-layout size / iOS blank open (#355):
  • #40: keep the native view hidden until the first successful render/fit so transitions do not flash an empty or mid-load surface
  • #127: harden first layout fit — defer document open until a non-zero size, re-fit when the platform view settles after the first paint
  • #190: iOS defers PDFDocument open until usable bounds, reports missing/unreadable/corrupt/empty documents via onError, and forces a layout pass after attach so the PDF is not stuck blank until background/foreground
• Includes everything in 1.5.0-beta.4

• Document Android AcroForm / fillable form field rendering limits: Pdfium paints /AP appearance streams and does not regenerate them like Adobe; producer workarounds for broken appearances (#303, #354)
• Includes everything in 1.5.0-beta.3

• Add first-class onTap callback (Dart + Android + iOS) so single taps are reported from the native PDF view; prefer this over gestureRecognizers + TapGestureRecognizer (#133, #353)
• Includes everything in 1.5.0-beta.2

• Document iOS platform-view composition limits for ColorFiltered / ShaderMask / BackdropFilter over PDFView, with official Flutter evidence and workarounds (#213, #352)
• Includes everything in 1.5.0-beta.1

Native language migration on both platforms. Includes everything in 1.4.5.

• Android: migrate the plugin implementation from Java to Kotlin (KGP 2.0.0, JVM target 17). Behavior verified by the existing 64-test native suite running against the Kotlin sources unchanged
• iOS: migrate the plugin implementation from Objective-C to Swift 5.9. The registered FLTPDFViewFlutterPlugin class name is preserved, NSException guards around PDFKit are kept via a small Objective-C shim target, and scroll observation moved to block-based KVO. Verified on both Swift Package Manager and CocoaPods (pod lib lint, dynamic + static)
• Fix a platform-view remount race: late creation callbacks from a disposed or remounted view can no longer complete the new controller with a stale instance
• Harden iOS setZoomLimits and align the podspec swift_version
• No public Dart API changes

Stable release of the 1.4.5-beta.1 → 1.4.5-beta.5 line; no code changes since 1.4.5-beta.5.

Highlights since 1.4.4 (see the beta sections below for the full list):

• BREAKING: minimum Flutter 3.32.0 / Dart 3.8.0
• BREAKING: Android platform views now use true hybrid composition (initExpensiveAndroidView) — fixes surface lock #263, EGL_NO_DISPLAY crash #280, blanking on rotation #9 / dialogs #182 / load #298, and GPU glitches #306
• BREAKING: Android external PDF links only auto-launch http/https; other schemes are reported through onLinkHandler instead
• iOS: fitPolicy (WIDTH / HEIGHT / BOTH) implemented for Android parity, page fit decoupled from autoSpacing #150, onError on bad passwords/documents #211, white background and continuous scrolling #204, Privacy Manifest #271
• Android: Java 17 toolchain #334, dispose/memory-leak fixes #261, absolute-path loading #266, libc++_shared.so packaging #287
• New API: minZoom / maxZoom #296, showScrollIndicators #337, onLoadComplete / onDraw, getCurrentPageSize(), getScreenshot(), getPosition() / setPosition(), getScale() / setScale(), reload(), setZoomLimits() #333
• Document remount when filePath / pdfData changes #181

Migration from 1.4.4 #

1. Raise your app to Flutter ≥ 3.32 and Dart ≥ 3.8.
2. Android PDF views now use expensive hybrid composition (true platform views); re-check layout and gesture behavior if you embed PDFView in complex widget trees.
3. Non-http(s) PDF links no longer auto-open — handle them yourself in onLinkHandler.

• Fix #150: iOS initial page fit no longer depends on autoSpacing (spacing vs zoom decoupled); re-fit after placeholder→real bounds and on rotation while preserving user zoom
• Implement fitPolicy (WIDTH / HEIGHT / BOTH) on iOS for parity with Android (iOS previously ignored the flag and always auto-fit the full page; default FitPolicy.WIDTH now matches Android)
• Add regression tests for #150 creation-param independence (Dart iOS/Android + Android Robolectric) and iOS fit-scale formula oracle
• Make standalone Android unit tests runnable: compileOnly Flutter embedding jar, fix android/settings.gradle, add scripts/run_android_unit_tests.sh

• BREAKING: Raise minimum Flutter version to 3.32.0 and Dart SDK to 3.8.0 (aligns with flutter_lints 6 and formatter.page_width)
• Android: switch platform views from texture hybrid composition (initSurfaceAndroidView) to true hybrid composition (initExpensiveAndroidView) — fixes Surface was already locked! #263, EGL_NO_DISPLAY quick-open crash #280, blank on rotation #9, blank after dialogs #182, blank on load #298, and GPU glitches #306
• Fix Android layout direction to follow ambient Directionality (was hardcoded RTL)
• Fix #181: remount platform view when filePath / pdfData changes so a new PDF can load
• Fix #261: release Pdfium/PDFKit resources on dispose (Android recycle race + iOS observers/document/channel)
• Restrict Android external PDF link auto-launch to http/https (avoids file:// crashes and unsafe schemes); still reports all schemes via onLinkHandler
• Serialize concurrent setPosition/setScale through a queue for any number of overlapping callers; null platform replies return false
• Compare pdfData via cached digests instead of a full per-byte scan on every rebuild
• Fix #268: avoid NaN CoreGraphics errors by initializing iOS PDFView with a non-zero frame
• Fix #204: iOS white background (not grey) and continuous vertical page scroll parity with Android
• Fix #266: load absolute filesystem paths via fromFile on Android (No content provider)
• Fix #287: pickFirst packaging for libc++_shared.so native merge conflicts
• Defer Android PDF load until the view has non-zero size; safer dispose before surface draw races
• Propagate nightMode setting updates to native Android view
• Document EagerGestureRecognizer for PDFView inside scrollables #265
• Fix Android external PDF links silently failing on API 30+ package visibility (resolveActivity pre-check)
• Fix controller deadlock: a failed setPosition/setScale call permanently hung all later position/scale calls
• Fix iOS silently showing a blank view for wrong/missing passwords — now fires onError (parity with Android)
• Fix iOS getCurrentPage/onPageChanged reporting a garbage index (NSNotFound) before a page is loaded
• Validate thumbnailRatio to (0, 1] (Dart assert + Android clamp) — out-of-range values crashed rendering
• Restructure Dart library into lib/src/ part files; public API unchanged
• Adopt flutter_lints 6.0 with zero analyzer issues; dartdoc for the entire public API
• Expand unit tests: controller method channel, native→Dart callbacks, document remount, creation settings
• Add 64 Android native unit tests (Robolectric/JUnit): URI handling, param parsing, link handler, thumbnail clamp
• Replace broken example widget test with home-screen / PDFScreen chrome coverage
• Fix Android setPage resolving before the jump executes; reload pages when nightMode changes; handle unescaped file: URIs on iOS

• Fixed issue #337: Added showScrollIndicators option to control native scroll indicator visibility.

• Fix iOS PDF view reporting not ready when it is on initial load
• Add minZoom and maxZoom to the README.md

• Fix iOS landscape PDF wrong initial zoom by preserving user-configured max scale factor #247
• Add configurable maxZoom and minZoom parameters #296
• BREAKING: Raise minimum Flutter version to 3.27.0 and Dart SDK to 3.6.0

• Update iOS deployment target to 13.0 in podspec and Package.swift (aligns with Flutter's own iOS 13.0+ requirement)
• Fix example app build error with undefined nightModeBackgroundColor parameter
• Add onLoadComplete callback triggered when the PDFView has loaded its document #333 @JaseElder
