WallBuilder class abstract
Defines how the wall will be built If you want to define your own algorithm, you will have to inherit from this abstract class, and implements the method WallBuilder.computeStonePositions.
Constructors
- WallBuilder()
- Default constructor.
- WallBuilder.standard()
-
Default WallBuilder implementation
factory
Properties
- direction → Axis
-
Define wall build direction, like ListView.direction input parameter.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- mainAxisSeparations → int
-
Define how many layers of the main axis the wall possess.
no setter
- reverse → bool
-
Define whether the wall must be displayed in reverse, like ListView.reverse input parameter.
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
assertNoDrawOutside(
Map< Stone, StoneStartPosition> stonesPositions) → void -
assertNoOverlap(
Map< Stone, StoneStartPosition> stonesPositions) → void -
build(
{required int mainAxisSeparations, required bool reverse, required Axis direction, required List< Stone> stones}) → WallBlueprint - Build the wall with scrollview parameters
-
computeSize(
Map< Stone, StoneStartPosition> stonesPositions) → WallSize - Compute the wall size from the stones positions.
-
computeStonePositions(
List< Stone> stones) → Map<Stone, StoneStartPosition> - Let you compute stone position for each stone. StonePositions must not overlap (stack not allowed), and not been drawn outside the wall (depending on WallBuilder.mainAxisSeparations).
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
