Methods

coerced(ViewPort decorated, {double minHeight = 0, double minWidth = 0, double maxHeight = double.infinity, double maxWidth = double.infinity}) → ViewPort

Provides a ViewPort which ViewPort.width and ViewPort.height values will be lower bounded by the provided minWidth and minHeight and upper bounded by maxWidth and maxHeight.

coercedMediaQuery(MediaQueryData data, {double minHeight = 0, double minWidth = 0, double maxHeight = double.infinity, double maxWidth = double.infinity}) → ViewPort

Provides a ViewPort which will produce the data's size values that are lower bounded by the given minHeight and minWidth and upper bounded by the given maxHeight and maxWidth

fixed({double height = double.infinity, double width = double.infinity}) → ViewPort

Provides a ViewPort which holds the given height and width statically. Arguments are set to double.infinity by default.

fromMediaQueryData(MediaQueryData data) → ViewPort

Provides a ViewPort that adapts the MediaQueryData.size interface

lowerBounded(ViewPort decorated, {double height = 0, double width = 0}) → ViewPort

Provides a ViewPort which ViewPort.width and ViewPort.height values will be lower bounded by the given ones.

lowerBoundedMediaQuery(MediaQueryData data, {double height = 0, double width = 0}) → ViewPort

Provides a ViewPort which will produce the data's size values that are lower bounded by the given height and width

maxOf(ViewPort left, ViewPort right) → ViewPort

Provides a ViewPort which chooses the maximal ViewPort.height and ViewPort.width value out of the two ViewPort implementations given

minOf(ViewPort left, ViewPort right) → ViewPort

Provides a ViewPort which chooses the minimal ViewPort.height and ViewPort.width value out of the two ViewPort implementations given

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

upperBounded(ViewPort decorated, {double height = double.infinity, double width = double.infinity}) → ViewPort

Provides a ViewPort which ViewPort.width and ViewPort.height values will be upper bounded by the given ones.

upperBoundedMediaQuery(MediaQueryData data, {double height = double.infinity, double width = double.infinity}) → ViewPort

Provides a ViewPort which will produce the data's size values that are upper bounded by the given height and width

Operators
