Matrix4

A recorded, replayable Matrix4 transform intent.

This class records constructors and mutating method calls, then Flet replays them in Flutter to build a real Matrix4 for Transform.matrix.

Properties

• ctor(_Matrix4Call) –

  Recorded constructor call.

• ops(list[_Matrix4Call]) –

  Ordered list of recorded mutating operations.

Methods

• diagonal3_values –

  Creates a matrix initialized with diagonal scale values.

• identity –

  Creates a matrix initialized with identity transform.

• multiply –

  Appends multiplication by another recorded matrix.

• rotate_x –

  Appends x-axis rotation operation in radians.

• rotate_y –

  Appends y-axis rotation operation in radians.

• rotate_z –

  Appends z-axis rotation operation in radians.

• rotation_z –

  Creates a matrix initialized with a z-axis rotation in radians.

• scale –

  Appends scale operation.

• set_entry –

  Appends raw matrix entry mutation.

• skew_x –

  Creates a matrix initialized with x-axis skew in radians.

• skew_y –

  Creates a matrix initialized with y-axis skew in radians.

• translate –

  Appends translation operation.

• translation_values –

  Creates a matrix initialized with translation components.

Properties

ctor class-attribute instance-attribute

ctor: _Matrix4Call = field(
    default_factory=lambda: _Matrix4Call(name="identity")
)

Recorded constructor call.

ops class-attribute instance-attribute

ops: list[_Matrix4Call] = field(default_factory=list)

Ordered list of recorded mutating operations.

Methods

diagonal3_values classmethod

diagonal3_values(
    x: Number, y: Number, z: Number
) -> Matrix4

Creates a matrix initialized with diagonal scale values.

identity classmethod

identity() -> Matrix4

Creates a matrix initialized with identity transform.

multiply

multiply(other: Matrix4) -> Matrix4

Appends multiplication by another recorded matrix.

rotate_x

rotate_x(angle: Number) -> Matrix4

Appends x-axis rotation operation in radians.

rotate_y

rotate_y(angle: Number) -> Matrix4

Appends y-axis rotation operation in radians.

rotate_z

rotate_z(angle: Number) -> Matrix4

Appends z-axis rotation operation in radians.

rotation_z classmethod

rotation_z(angle: Number) -> Matrix4

Creates a matrix initialized with a z-axis rotation in radians.

scale

scale(
    x: Number,
    y: Number | None = None,
    z: Number | None = None,
) -> Matrix4

Appends scale operation.

If only x is provided then uniform scale is used. If x and y are provided then 2D scale is used. If all three are provided then 3D scale is used.

set_entry

set_entry(row: int, col: int, value: Number) -> Matrix4

Appends raw matrix entry mutation.

skew_x classmethod

skew_x(angle: Number) -> Matrix4

Creates a matrix initialized with x-axis skew in radians.

skew_y classmethod

skew_y(angle: Number) -> Matrix4

Creates a matrix initialized with y-axis skew in radians.

translate

translate(x: Number, y: Number, z: Number = 0) -> Matrix4

Appends translation operation.

translation_values classmethod

translation_values(
    x: Number, y: Number, z: Number
) -> Matrix4

Creates a matrix initialized with translation components.
