live_cells 0.10.0

live_cells: ^0.10.0 copied to clipboard

• Initial release.

• Fix package directory structure

• Fix dart doc issues

New features:

• Stronger guarantees that a StoreCell will not hold an outdated value
• Shorthand .cell property for creating constant value cells
• Shorthand List.computeCell method for creating multi-argument computational cells
• Arithmetic and comparison operator overloads to create computational cells directly using expressions such as a + b

Breaking changes:

• ValueCell is no longer a ValueListenable
• ValueCell.addListener and ValueCell.removeListener are replaced with addObserver and removeObserver
• New CellObserver interface for observing changes to the values of cells
• ValueCell.listenable property provided to use ValueCell as a ValueListenable

• Fix issues with examples in README

• Fix issue with List.computeCell method
• Fix issues with unit tests

• Fix issue with CellTextField

New features:

• Mutable computational cells
• Batch updates
• CellWidget base class for creating widgets make use of cells
• CellWidgetBuilder for creating CellWidget's without subclassing
• New widgets in widgets library:
  • CellCheckbox
  • CellCheckboxListTile
  • CellRadio
  • CellRadioListTile
  • CellSlider
  • CellSwitch
  • CellSwitchListTile
• Shorthand List.computeWidget method for creating widgets which depend on multiple cells

Breaking changes:

• MutableCell is now an interface with a factory constructor
• CellObserver interface methods now take observed cell as arguments
• Removed CellBuilder

• Bug fixes

• Simplify implementation of CellWidget. Subclasses now override build instead of buildChild.

• Bug fixes

New features:

• ValueCell.computed constructor for creating computed cells with dynamic dependencies
• MutableCell.computed constructor for creating mutable computed cells with dynamic dependencies
• CellWidget can now also track the cells it depends on at runtime
• mutableString extension method on MutableCell's holding an int, double, num or string

Breaking changes:

• CellWidget.cell method has been moved to CellListeners mixin
• CellWidgetBuilder has been removed in favour of CellWidget.builder constructor

Improvements:

• Simplified examples demonstrating core concepts only
• Simplified and streamlined API
• Improved README
• Bug fixes

• Fix typos and bugs in examples in README

• Fix potential issues

New features:

• Maybe type and MaybeCell for error handling
• errorValue argument of mutableString method to control value in case of errors during parsing
• Remove restriction that arguments of mutable computed cells be mutable cells

Breaking changes:

• Add shouldNotifyAlways property to CellObserver interface

Improvements and bug fixes:

• Simplify implementation of CellInitializer.cell
• Allow updated cell value to be accessed even when the cell has no observers
• Fix bug in BuildContext.cell method
• Fix bug in CellTextField

• Fix potential issues
• Fix typos and improve README

New features:

• ValueCell.watch and CellInitializer.watch for calling a function whenever the values of cells change.
• State restoration of cells with RestorableCellWidget

New features:

• Ability to access the previous values of cells with .previous
• Ability to abort a cell value update with ValueCell.none()
• and, or, not and select methods on bool cells
• Exception handling using onError and error
• Clarified how exceptions are propagated between cells

• Correct typos and errors in readme examples

New features:

• Constant bool, null, Enum and Duration cells can now be created with the cell property, e.g. true.cell.
• Utilities for working with cells holding a Duration.
• CellObserverModel for creating classes which observe one or more cells
• Add selection cell parameter to CellTextField constructor for observing and controlling the field's selection.

• Fixed bug with accessing previous cell values

New features:

• Keyed cells, cells with the same key reference a shared state.
• Lightweight mutable computed cells.
• CellExtension annotation for automatically generating ValueCell accessors for classes, using the live_cell_extension package (which will be released soon).

This release also comes with major changes to the implementation. These changes are only breaking to code which creates user-defined ValueCell subclasses:

• Removed the following internal implementation classes and mixins from the public API:
  • EqCell
  • NeqCell
  • NotifierCell
  • CellEquality
  • CellListeners
  • ObserverCell
