- RestrictedPositions({double maxCoverage = 0.8, double minCoverage = double.negativeInfinity, StackAlign align = StackAlign.left, double infoIndent = 0.0, StackLaying laying = StackLaying.last, LayoutDirection layoutDirection = LayoutDirection.horizontal})
Properties
- align → StackAlign
-
Alignment
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- infoIndent → double
-
The additional space between an info item (if exists) and other items.
Info item usually has information about hidden items. Something like: (+5)
final
- laying ↔ StackLaying
-
The way to tile items.
getter/setter pair
- layoutDirection → LayoutDirection
-
final
- maxCoverage → double
-
Define maximum items coverage.
If maxCoverage is negative the gape between item exists.
It is measured as a percentage, for example:
minCoverage = 0.5 means 50% of coverage
minCoverage = 0.81 means 81% of coverage
final
- minCoverage → double
-
Define minimum items coverage.
If minCoverage is negative the gape between item exists.
It is measured as a percentage, for example:
minCoverage = 0.5 means 50% of coverage
minCoverage = 0.81 means 81% of coverage
final
- runtimeType → Type
-
A representation of the runtime type of the object.
