FixedTrackSize class

Sizes the track to a specific number of pixels.

This is the cheapest way to size a track.

Inheritance

• Object
• TrackSize
• FixedTrackSize

Constructors

FixedTrackSize(double sizeInPx, {String? debugLabel})

const

Properties

debugLabel → String?

A label that is included in debug output

final, inherited

flex → double?

The flex factor to apply to the track if there is any room left over when laying out the grid. The remaining space is distributed to any tracks with flex in proportion to their flex value (higher values get more space).

no setter, inherited

hashCode → int

The hash code for this object.

no setter, override

isFlexible → bool

Returns whether this sizing function consumes space left over from the initial sizing of the grid.

no setter, inherited

isIntrinsic → bool

Returns whether this sizing function requires measurement of a track's items to resolve its size.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

sizeInPx → double

The size (width for columns, height for rows) the track should occupy in logical pixels.

final

Methods

debugFillProperties(DiagnosticPropertiesBuilder properties) → void

Add additional properties associated with the node.

override

isFixedForConstraints(TrackType type, BoxConstraints gridConstraints) → bool

Returns whether this size can resolve to a fixed value provided the grid's box constraints.

override

maxIntrinsicSize(TrackType type, Iterable<RenderBox> items, {required double crossAxisSizeForItem(RenderBox)}) → double

The ideal cross axis size of this track. This must be equal to or greater than the minIntrinsicSize for the same type. The track might be bigger than this size, e.g. if the track is flexible or if the grid's size ends up being forced to be bigger than the sum of all the maxIntrinsicSize values.

override

minIntrinsicSize(TrackType type, Iterable<RenderBox> items, {double crossAxisSizeForItem(RenderBox)?}) → double

The smallest width (for columns) or height (for rows) that a track can have.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode

Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.

inherited

toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String

A string representation of this object.

inherited

toStringShort() → String

A brief description of this object, usually just the runtimeType and the hashCode.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
