This might help you determine the angle
eg :

Try using these values:
LinearGradient( begin: Alignment(-1.0, -2.0), end: Alignment(1.0, 2.0),
Or event better
LinearGradient( begin: Alignment(-1.0, -4.0), end: Alignment(1.0, 4.0),
Y: parameter description
The distance fraction in the vertical direction.
A value of -1.0 corresponds to the topmost edge. A value of 1.0
corresponds to the bottommost edge. Values are not limited to that range;
/// values less than -1.0 represent positions above the top, and values /// greater than 1.0 represent positions below the bottom.
Use Alignment.topLeft
and Alignment.bottomRight
LinearGradient( colors: [Colors.cyanAccent, Colors.amberAccent], begin: Alignment.topLeft, end: Alignment.bottomRight, tileMode: TileMode.clamp),
