DefaultViewport class

This is the default viewport if you want no transformation. The raw canvasSize is just propagated to the effective size and no translation is applied. This basically no-ops the viewport.

DefaultViewport()

Properties

canvasSize ↔ Vector2?
This returns the real widget size (well actually the logical Flutter size of your widget). This is the raw canvas size as it would be without any viewport.
getter/setter pairinherited
effectiveSize → Vector2
This returns the effective size, after viewport transformation. This is not the game widget size but for all intents and purposes, inside your game, this size should be used as the real one.
no setteroverride
hashCode → int
The hash code for this object.

runtimeType → Type
A representation of the runtime type of the object.

Methods

apply(Canvas c) → void
Applies to the Canvas all necessary transformations to apply this viewport.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
projectVector(Vector2 vector) → Vector2
Converts a vector in the world space to the screen space.
override
render(Canvas c, void renderGame(Canvas)) → void
This transforms the canvas so that the coordinate system is viewport- -aware. All your rendering logic should be put inside the lambda.
inherited
resize(Vector2 newCanvasSize) → void
This configures the viewport with a new raw canvas size. It should immediately affect effectiveSize and canvasSize. This must be called by the engine at startup and also whenever the size changes.
override
scaleVector(Vector2 vector) → Vector2
Converts a vector representing a delta in the world space to the screen space.
override
toString() → String
A string representation of this object.
inherited
unprojectVector(Vector2 vector) → Vector2
Converts a vector in the screen space to the world space.
override
unscaleVector(Vector2 vector) → Vector2
Converts a vector representing a delta in the screen space to the world space.

Operators

operator ==(Object other) → bool
The equality operator.
