A GridDelegate the places its children in order throughout the grid.
Subclasses must still provide a mechanism for sizing the grid by implementing getGridSpecification, and should also provide efficent versions of the intrinsic sizing functions (getMinIntrinsicWidth and company).

Constructors
- GridDelegateWithInOrderChildPlacement({double columnSpacing: 0.0, double rowSpacing: 0.0, EdgeInsets padding: EdgeInsets.zero })
-
Initializes columnSpacing, rowSpacing, and padding for subclasses.
Properties
- columnSpacing → double
-
The horizontal padding between columns.
read-only - padding → EdgeInsets
-
Insets for the entire grid.
read-only - rowSpacing → double
-
The vertical padding between rows.
read-only - hashCode → int
-
Get a hash code for this object.
read-only, inherited - runtimeType → Type
-
A representation of the runtime type of the object.

Operators
-
operator ==(
other) → bool -

Methods
-
getChildPlacement(
GridSpecification specification, int index, Object placementData) → GridChildPlacement -
Override this method to control where children are placed in the grid.
-
shouldRelayout(
GridDelegateWithInOrderChildPlacement oldDelegate) → bool -
Override this method to return true when the children need to be laid out.
-
getGridSpecification(
BoxConstraints constraints, int childCount) → GridSpecification -
Override this method to control size of the columns and rows.
inherited -
getMaxIntrinsicHeight(
double width, int childCount) → double -
Returns the smallest height beyond which increasing the height never decreases the preferred width.
inherited -
getMaxIntrinsicWidth(
double height, int childCount) → double -
Returns the smallest width beyond which increasing the width never decreases the preferred height.
inherited -
getMinIntrinsicHeight(
double width, int childCount) → double -
Return the minimum height that this grid could be without failing to paint its contents within itself.
inherited -
getMinIntrinsicWidth(
double height, int childCount) → double -
Returns the minimum width that this grid could be without failing to paint its contents within itself.
inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited -
toString(
) → String -
Returns a string representation of this object.
