Where is ConstraintLayout source code located?

Question

Where can I find the source code for the android ConstraintLayout? I can\'t find it in the support framework repository and even in Google search.

Answer 1

Its source code is here: https://android.googlesource.com/platform/frameworks/opt/sherpa/+/studio-3.0/constraintlayout/src/main/java/android/support/constraint/ConstraintLayout.java

The Android SDK search extension adds a "View source" button on d.android.com reference, which helped me to get this link
