The following functions are supported:

1. build flexible layouts with constraints
    1. leftToLeft
    2. leftToRight
    3. rightToLeft
    4. rightToRight
    5. topToTop
    6. topToBottom
    7. bottomToTop
    8. bottomToBottom
    9. baselineToTop
    10. baselineToBottom
    11. baselineToBaseline
2. margin and goneMargin
3. clickPadding (quickly expand the click area of child elements without changing their actual size.
   This means that the click area can be shared between child elements without increasing nesting.
   Sometimes it may be necessary to combine with z-index)
4. visibility control
5. constraint integrity hint
6. bias
7. z-index
8. translate
9. percentage layout
10. guideline
11. constraints and widgets separation
12. barrier
