+0.8.1-beta:
+The first version published to pub.dev.
+
+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.)
+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
