getter/setter pairinherited
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 pairinherited

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
inherited
cellRange(String singlePT) → (String, String)?
inherited
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)
inherited
containsRatioChangeListener(String tag) → bool
inherited

inherited
createVirtual(String singlePT, [ScreenParams? givenColumns]) → ScreenContext
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).
