startAngle property
final
The angle in radians at which stop 0.0 of the gradient is placed.
The angle is measured in radians clockwise from the positive x-axis.
Values outside the range [0, 2π] are normalized to the equivalent angle
within this range using modulo arithmetic.
The gradient will be painted in the sector between startAngle and endAngle. The behavior outside this sector is determined by tileMode.
Defaults to 0.0.
