Constructors

MercosulPlate(String plate, {double? width, double? height, BrazilPlateCategory category = BrazilPlateCategory.PARTICULAR, String countryText = 'BRASIL', String countryAcronymLetters = 'BR', String countryFlagAsset = 'assets/images/brazil.png', String mercosulLogoAsset = 'assets/images/merco.png'})
Class constructor. To obtain the original aspect ratio of a real license plate, only provide a value for width OR height, so it will keep the original proportion automatically. If a value is provided for these two properties, then the original aspect ratio will not be take in account. If neither are provided, the value of _defaultWidth will be used.
const

Properties

category BrazilPlateCategory
The plate's category which determines the default color set
final
countryAcronymLetters String
The two letters printed at the bottom left position. Always converted to uppercase. Defaults to "BR"
final
countryFlagAsset String
The name of the image asset that will be placed in the top right corner. Considers a relative path from the root of the assets folder. Defaults to brazil.png
final
countryText String
The string that represents the text which will be positioned at the top of the licence plate, generally the name of the country. Always converted to uppercase. Defaults to "BRASIL"
final
hashCode int
The hash code for this object.
@nonVirtualread-onlyinherited
height double?
The height that the whole widget will take. If left null, then the original proportion factor will be used to calculate this value from the width.
final
key Key?
Controls how one widget replaces another widget in the tree.
finalinherited
mercosulLogoAsset String
The path of the logo asset that will be placed in the top left corner. Considers a relative path from the root of the assets folder. Defaults to merco.png
final
plate String
The letters and numbers drawn in the licence plate
final
realHeight double
Evaluates the real height that will be considered while drawing the widget. If a height value was explicitly passed to object's constructor, then this value will be used. Otherwise, it infers a value for height from the width property, consering the original proportional factor.
read-only
realWidth double
Evaluates the width value that will be used to draw the widget. If a value is passed to the constructor, then this value will be used. Otherwise, it checks if a value has been passed to height and calculates the width using the original proportion factor. If both width and height are nulls, then the value setted for _defaultWidth will be used.
read-only
runtimeType Type
A representation of the runtime type of the object.
read-onlyinherited
width double?
The width that the whole widget will take. If null, the width value will be infered from the height value. If height is null, then the _defaultWidth value will be considered.
final
