#<\/span> Eliminating Jank<\/h3>\nLuckysmg, an open-source contributor. They realized that they could reduce the time it took to obtain the next drawable layer from the Metal driver. To gain that advantage, you must change the FlutterViews<\/strong><\/em> background color to anything other than null. This modification removes poor frame rates from newer iOS 120Hz monitors. It can treble the frame rate in some circumstances. This aided in the resolution of several GitHub problems. This modification was so significant that included a hotfix in the 3.7 release.<\/p>\nTo prevent delaying vsync events from the platform thread, They moved the loading of local pictures from the platform thread to the Dart thread in the 3.7 stable release. Users, however, found that the increased work on the Dart thread produced considerable jank. They relocated the opening and decoding of local pictures from the Dart thread to a background thread in this version. This update removes the possibility of extended pauses on displays with a large number of local pictures, while also avoiding delaying sync events. This update lowered the load time for several simultaneous pictures in half in local testing and automated benchmarks.<\/p>\n
It continues to optimize Flutter’s new internal DisplayList structure. That included an R-Tree-based culling method in this version. This method eliminates the need for renderer to conduct drawing operations considerably early. This optimization, for example, speeds up a custom painter whose output fails offscreen. As microbenchmarks revealed a 50% reduction in DisplayList processing time. Apps with clipped custom paints may notice varying degrees of improvement. The degree of improvement is determined by the quantity and complexity of hidden draw processes.<\/p>\n
#<\/span> Reducing iOS Startup Latency<\/h3>\nAn inefficient identifier lookup approach in app packages increases app starting delay. This startup delay increases in direct proportion to the size of the app. They corrected the bundle identifier lookup in this version. In a big production application, this decreased startup latency by 100ms or around 30-50%.<\/p>\n
#<\/span> Reducing Size<\/h3>\nSkParagraph<\/strong><\/em> is the default library for text shape, layout, and rendering in Flutter. They added a flag to force the use of the legacy libtxt<\/strong><\/em> and minikin<\/strong><\/em> libraries. They removed libtxt and minikin<\/strong><\/em>, as well as their flag, from this version since They have complete trust in SkParagraph. This decreases the compressed size of Flutterby by 30KB.<\/p>\n#<\/span> Stability<\/h3>\nIt enabled an Android functionality late in our rendering pipeline in the 3.0 release. This Android feature made advantage of powerful GPU driver capabilities. When only one “dirty” region changes, these driver features redraw less of the screen. This was also applied to previous optimizations to graphics pipeline that had similar results. Although their benchmark findings were encouraging, two difficulties arose. For starters, the most improved benchmark may not represent realistic use scenarios. Second, the devices and Android versions that enabled this GPU driver capability were few. They removed the partial repaint capability for Android due to limited advancements and support.<\/p>\n
When utilizing the Skia backend, the functionality remains active on iOS. They plan to make it available with Impeller in a future version.<\/p>\n
API Improvements<\/h2>\n
\n#<\/span> APNG Decoder<\/h3>\nFlutter 3.10 solves one of the most often-raised concerns. It now supports decoding APNG<\/strong><\/em> images. APNG<\/strong><\/em> images may be loaded using Flutter’s current image-loading APIs.<\/p>\n#<\/span> Image Loading API Improvements<\/h3>\nFlutter’s valued Director of Engineering, tvolkert, has improved the picture-loading APIs in dart:ui<\/strong><\/em>. They have included a new function called instantiateImageCodecWithSize<\/strong><\/em>. This enables the use case of loading a picture that matches the following three criteria:<\/p>\n\n- At the moment of loading, the aspect ratio is unknown.<\/li>\n
- a bounding box restriction.<\/li>\n
- an original aspect ratio limitation.<\/li>\n<\/ol>\n
As an example, suppose an application wants to display one image from a pool of options loaded over the network.<\/p>\n
For iOS<\/h2>\n
\n#<\/span> Wireless Debugging<\/h3>\nYou may now use your Flutter iOS applications without a wire to run and hot reload them! After successfully wirelessly connecting your iOS device to Xcode<\/strong>, you can use Flutter Run to deploy your app to that device. If you have problems, make sure the network icon displays next to your device in Window<\/strong> > Devices and Simulators<\/strong> > Devices<\/strong>.<\/p>\n#<\/span> Wide Gamut Image Support<\/h3>\nFlutter applications on iOS can now display a wide gamut of photos accurately. To enable wide gamut support, the app must use Impeller and add the FLTEnableWideGamut setting in the Info.plist file.<\/p>\n
#<\/span> Spellcheck Support<\/h3>\nThe SpellCheckConfiguration()<\/strong><\/em> widget on iOS now by default supports Apple’s spell-check service. Set the spellCheckConfiguration<\/strong><\/em> parameter in CupertinoTextField<\/strong><\/em> to utilize this widget.<\/p>\n#<\/span> Adaptive Checkbox and Radio<\/h3>\nThe Cupertino collection now includes the CupertinoCheckBox<\/strong><\/em> and CupertinoRadio<\/strong><\/em> widgets. They design checkbox and radio button components that are consistent with Apple’s design.<\/p>\nThe. adaptive constructors were introduced to the Material checkbox and radio widgets. On iOS and macOS, these constructors make use of the Cupertino widgets. Material widgets are used on various platforms.<\/p>\n
#<\/span> Cupertino Animations, Transitions, and Colors are Being Refined<\/h3>\nTo match SwiftUI, Flutter 3.10 updated certain animations, transitions, and colors. These enhancements include:<\/p>\n
\n- The cupertinoPageRoute<\/strong><\/em> transition is being updated.<\/li>\n
- CupertinoSliverNavigationBar<\/em> now has a title magnification animation.<\/li>\n
- CupertinoColors<\/strong><\/em> has been updated with numerous new iOS system colors.<\/li>\n<\/ol>\n
#<\/span> PlatformView Performance<\/h3>\nFlutter throttles the refresh rate on iOS when PlatformViews<\/strong><\/em> are on the screen to avoid jank. When the app shows dynamic or scrollable PlatformViews<\/strong><\/em>, app users will see this<\/p>\n#<\/span> Plugins for macOS and iOS can Use Similar Code<\/h3>\nIn the
