Properties

column → int
no setter
columnSpanPTs → List<String>
no setter
contextScreenColorMap ↔ Map<String, Color>
getter/setter pair
contextScreenPatternsMap ↔ Map<int, Map<String, Map<String?, String?>>>
用于拼画设置(把相临的两个屏幕拼合或者拆开)
getter/setter pair
currentPattern → String
no setter
currentPatternNullable ↔ String?
getter/setter pair
currentRatio ↔ double?
getter/setter pairinherited
currentSize → Size?
no setterinherited
currentSizeRect ↔ Rect?
getter/setter pairinherited
debug ↔ DebugToolContext?
getter/setter pair
focusPageMode ↔ FocusPageMode
getter/setter pair
fullscreenAspectRatioSize → Size?
no setter
hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
no setterinherited
lastPattern → String?
no setter
mode ↔ RUNMODE
getter/setter pair
ratioList → List<RatioChangeListener>
no setterinherited
row → int
初始化 Key 跟测量相关
no setter
rowColumn ↔ RCPair
更改行列会导致 重新布局 gKeys.clear(); 需要测量 gKeyMappedValues.clear(); 恢复 语境初始分屏模式
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
singleAspectRatioSize ↔ Size?
更改模式不引起重新布局 更改屏幕比例导致 重新测量 gKeyMappedValues.clear();
getter/setter pair
singles → List<String>
no setter
sizeList → List<SizeChangeListener>
no setterinherited
tailColumnExpand ↔ TailColumnExpand
getter/setter pair
tailColumnExpandAvailable → bool
no setter

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
addRatioChangeListener(RatioChangeListener listener, {Size? initSize, String tag = DEFAULT_TAGNAME}) → void
inherited
addSizeChangeListener(SizeChangeListener listener, {Size? initSize, String tag = DEFAULT_TAGNAME}) → void
inherited
autoSetPatternByColumnNum() → void
cellRange(String singlePT) → (String, String)?
columnSplits(String singlePT) → List<double> Function(Size size)?
根据当前 singlePT 获得 - 的分割比例，用于绘制拼屏网格线(物理拼缝，不包含在grid中)
containsRatioChangeListener(String tag) → bool
inherited
containsSizeChangeListener(String tag) → bool
inherited
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
override
genContextPTColumnsLR(List<int> columnsLR) → String?
genContextPTColumnsRL(List<int> columnsRL) → String?
handSet(ScreenHandset setting) → void
isTailInclude(String singlePT) → dynamic
检查屏幕语境是否包含尾屏
measuredCell(int column, [int row = 1]) → Rect?
measuredPT(String singlePT) → Rect?
包含 cell-x-1 的情况
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
notifyRatioChange(Size size, double newRatio, double? oldRatio) → void
inherited
notifySizeChange(Rect newSize, Rect? oldSize) → void
inherited
offsetFromGrid({int? column, int row = 1, String? singlePT, required NamedLine vertical, required NamedLine horizontal, bool isGlobal = true}) → Offset?
paintRect(String singlePT) → Rect?
rectFromGrid({int? column, int row = 1, String? singlePT, required List<NamedLine> verticals, required List<NamedLine> horizontals, bool isGlobal = true}) → Rect?
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
removeRatioChangeListener(RatioChangeListener listener, {String name = DEFAULT_TAGNAME}) → bool
inherited
removeRatioChangeTag(String tag) → void
inherited
removeSizeChangeListener(SizeChangeListener listener, {String tag = DEFAULT_TAGNAME}) → bool
inherited

inherited
resetPattern() → void
screenPTFromColumnsLR(int column) → String
toString() → String
A string representation of this object.
