dough's Issues

Multi-touch support - Pinchable or SqueezableDough()

Multi-touch

This would let you pinch and squeeze the dough from two or more sides, and the dough would droop down out or pile up, away from the forces applied to it, just like real dough. Currently, attempting to pinch the dough or use multi-touch make the dough warp across the screen.

Long press Draggable Dough

Long press Draggable, to have more control to move Dough Items inside List View

Describe the solution you'd like

Reorderable List Dough

The draggable dough widget feels awesome. The same concept could be applied to a ReorderableList.

A possible implementation would be:

• The user presses on a reorderable list item.
• The user drags the list item in a direction. Similar to DraggableDough, the list item will appear to stick to its slot. Once a drag threshold is met, the list item will elastically snap to the user's finger and will be freely movable/reorderable.

Similar to this feature, except for reorderable lists instead:

Don't know what you code in but please format your code.

Use the Provider package instead of Inherited widget

This applies to the DoughRecipe class. It'd be nice if Provider was used instead of InheritedWidget.

Use this to update the rolling sum of the gyro widget and other related functionality.

[suggestion] A dough widget that is draggable and "detaches" e.g. a list item

A squishy item that "comes off" when dragged somewhere else would be awesome.

Gyro Dough

A widget that morphs based on how a user moves their mobile device around in physical space (using gyro sensors). If a user shakes their phone to the left (or maybe tilts it to the left), a widget wrapped in the GyroDough widget will droop left, as if it were a real piece of dough.

Migrate to null safety

Dart team recommends that packages migrate to null-safety. Create/test a null safety API for dough.

'package:flutter/src/widgets/framework.dart': Failed assertion: line 4138 pos 12: '_debugLifecycleState != _ElementLifecycle.defunct': is not true.

Hello. Am getting the above error when I pop the containing page. Am I doing something wrong?

Love the package otherwise, thanks!

════════ Exception caught by widgets library ═══════════════════════════════════
The following assertion was thrown while finalizing the widget tree:
_DoughState#6945b(ticker active) was disposed with an active Ticker.

_DoughState created a Ticker via its SingleTickerProviderStateMixin, but at the time dispose() was called on the mixin, that Ticker was still active. The Ticker must be disposed before calling super.dispose().

Tickers used by AnimationControllers should be disposed by calling dispose() on the AnimationController itself. Otherwise, the ticker will leak.

The offending ticker was: Ticker(created by _DoughState#6945b(lifecycle state: created))
The stack trace when the Ticker was actually created was:

[suggestion] Dough 3D rotation

I was messing around to achieve the realistic scaling mentioned in the README

In DraggableOverlayDoughTransformer.createDoughMatrix() I made this change:

@override
  Matrix4 createDoughMatrix() {
    final adhesiveDx = delta.x * t / recipe.adhesion;
    final adhesiveDy = delta.y * t / recipe.adhesion;

    Matrix4 translate;
    if (applyDelta) {
      if (snapToTargetOnStop) {
        final dx = -delta.x * (controller.isActive ? 1 : t);
        final dy = -delta.y * (controller.isActive ? 1 : t);
        translate = Matrix4.translationValues(
              dx + adhesiveDx,
              dy + adhesiveDy,
              0,
            )
        //--- Rotate in 3 dimensions ---------------
            * (Matrix4.identity()
              ..setEntry(3, 2, 0.01)
              ..rotateY(-(dx + adhesiveDx) * 0.01)
              ..rotateX((dy + adhesiveDy) * 0.01));
        //-------------------------------------------
      } else {
        translate = Matrix4.translationValues(
          -delta.x + adhesiveDx,
          -delta.y + adhesiveDy,
          0,
        );
      }
    } else {
      translate = Matrix4.translationValues(adhesiveDx, adhesiveDy, 0);
    }

    return translate * bendWithDeltaMatrix() * expansionMatrix();
  }

Is that what you are looking for?

Describe the bug
Operand of null-aware operation '!' has type 'WidgetsBinding' which excludes null.

Sensors introduces platform dependency

Sensors introduces platform dependency for android and iOS and does not include the mac/linux/windows platform. This is causing the package to lose pub points.

Find a way to support accelerometer functionality on mobile platforms (for GyroDough) while maintaining support for web/desktop platforms.

Use the equatable package instead of raw equals implementation

Some classes (such as DoughRecipe and some of its fields) override equality checking manually using the == operator and hashcode() override. This is prone to error as more fields are added. Replace this equality checking implementation with the equatable package equality checking implementation.
