toString method Null safety
override
A string representation of this object.
Some classes have a default textual representation,
often paired with a static parse
function (like int.parse).
These classes will provide the textual representation as
their string representation.
Other classes have no meaningful textual representation
that a program will care about.
Such classes will typically override toString
to provide
useful information when inspecting the object,
mainly for debugging or logging.
Implementation
@override
String toString() {
final List<String> properties = <String>[
'size: $size',
'devicePixelRatio: ${devicePixelRatio.toStringAsFixed(1)}',
'textScaleFactor: ${textScaleFactor.toStringAsFixed(1)}',
'platformBrightness: $platformBrightness',
'padding: $padding',
'viewPadding: $viewPadding',
'viewInsets: $viewInsets',
'alwaysUse24HourFormat: $alwaysUse24HourFormat',
'accessibleNavigation: $accessibleNavigation',
'highContrast: $highContrast',
'disableAnimations: $disableAnimations',
'invertColors: $invertColors',
'boldText: $boldText',
'navigationMode: ${navigationMode.name}',
'gestureSettings: $gestureSettings',
'displayFeatures: $displayFeatures',
