Grid class

Container for holding 9x9 cell matrix For an example of what a 9x9 grid looks like, see Position

Constructors

Grid()

Constructs a grid with matrix of cells whose value is all empty

Grid.fromMap(Map<String, dynamic> map)

Serialization

factory

Properties

change → Stream

no setter

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

cellAt(Position pos) → Cell

Getters and setters I can only make these comments so interesting and no more :l

getColumn(int colNum) → List<Cell>

Returns a list of Cell at row # colNum

getRow(int rowNum) → List<Cell>

Returns a list of Cell at row # rowNum

getSegment(Position position) → List<Cell>

Returns a list of Cell at segment defined by position.segment

isColumnViolated(Position position) → bool

Determines if a column is violated by using a Set of Cell values If, while building this Set, a duplicate value is going to be added, then this column is violated No violations are counted for empty cells (cells whose value is 0)

isRowViolated(Position position) → bool

Determines if a row is violated by using a Set of Cell values If, while building this Set, a duplicate value is going to be added, then this row is violated No violations are counted for empty cells (cells whose value is 0)

isSegmentViolated(Position position) → bool

Determines if a segment is violated by using a Set of Cell values If, while building this Set, a duplicate value is going to be added, then this segment is violated No violations are counted for empty cells (cells whose value is 0)

matrix() → List<List<Cell>>?

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

pregenFirstRow() → void

Pre-generates the first row of grid with randomized values

startListening() → void

Attach listeners for each cell - the grid is now listening for changes to any cell, and will broadcast them through _onChange

stopListening() → void

Detach all subscriptions to cell streams - stop listening to changes

toMap() → Map<String, dynamic>

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
