added in: 1.6.0 style

If any value, passed to EdgeInsets.fromLTRB, equals 0, then EdgeInsets.fromLTRB should be replaced with EdgeInsets.only passing all non-zero values. If passed values are symmetric, then EdgeInsets.fromLTRB or EdgeInsets.only should be replaced with EdgeInsets.symmetric.

Example

Bad:

EdgeInsets.fromLTRB(8, 0, 8, 0)
EdgeInsets.fromLTRB (8, 0, 0, 0)
EdgeInsets.only(left: 16, right: 16)
EdgeInsets.fromLTRB(8, 8, 8, 8)

Good:

EdgeInsets.symmetric(horizontal: 8)
EdgeInsets.only(left: 8)
EdgeInsets.symmetric(horizontal: 16)
EdgeInsets.all(8)
