Flutter 3.18 beta (December 5, 2023)

Flutter Framework

Notable commits

Added support for Apple system fonts

Flutter text now looks a little more compact and a little more native on iOS. For the "Text" font this will be more secure in the future against possible changes to Apple's API. For the "Display" font, this will now work correctly when it didn't before.

• Refactor to use Apple system fonts by @MitchellGoodwin in #137275

Adaptive Switch

The implementation of Switch.adaptive no longer depends on the Cupertino library. Everything is handled by the Material component and there are no longer any switch properties that are not supported by the .adaptive version. We also added support for customizing the appearance of adaptive components.

• Adaptive Switch by @QuncCccccc in #130425

Scrolling

Flutter used to scroll twice as fast if you dragged two fingers. You can now configure the default ScrollBehavior with MultiTouchDragStrategy.latestPointer to get number-of-fingers-agnostic scrolling behavior. We also updated scrolling so now if you start dragging or tap while a scroll is underway the scroll stops as expected.

• Introduce multi-touch drag strategies for DragGestureRecognizer by @xu-baolin in #136708
• Fix 2D tap to stop scrolling by @Piinks in #138442

Increased access to text widgets’ state

We added support for a MaterialStatesController in TextField and TextFormField so that you can listen to MaterialState changes.

• TextField and TextFormField can use a MaterialStatesController by @Renzo-Olivares in #133977

UndoHistory stack

We fixed a problem where the undo/redo history could disappear on Japanese keyboards, and made it so you can now modify the UndoHistory stack.

• Add undoStackModifier to UndoHistory by @Renzo-Olivares in #138674

Visuals and animations

This beta includes many improvements to visuals and animations across the Flutter Framework, most notably:

• Make UnderlineInputBorder consistent by @bernaferrari in #124153
• Introduce AnimationStyle by @TahaTesser in #137945
• Fix sliver persistent header expand animation by @feduke-nukem in #137913
