[Flow] Chain wrapping produces unexpected results with layout_constraintWidth_min

[smelfungus]

Hello!
Having the following layout:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  tools:context=".MainActivity">

  <androidx.constraintlayout.helper.widget.Flow
    android:layout_width="0dp"
    android:layout_height="0dp"
    app:constraint_referenced_ids="textViewA,textViewB"
    app:flow_wrapMode="chain"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

  <TextView
    android:id="@+id/textViewA"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimaryContainer"
    android:text="This text should shrink up to 120 dp"
    app:layout_constraintWidth_min="120dp" />

  <TextView
    android:id="@+id/textViewB"
    android:layout_width="400dp"
    android:layout_height="wrap_content"
    android:background="?attr/colorTertiaryContainer"
    android:text="This text should not shrink, layout_width is fixed" />

</androidx.constraintlayout.widget.ConstraintLayout>

Flow chain wrapping is showing unexpected behaviour:

It would be nice to respect layout_constraintWidth_min and do a chain wrapping instead of clipping.

Thanks for reporting the issue! However, we won't be able to fix this issue in the short term.
With the use case you shared, the Flow helper could be a better alternative.

@jswong65 thank you for your answer! I'm facing this issue with androidx.constraintlayout.helper.widget.Flow. Is there any additional flow helper that may come to the rescue?

The comment I made is actually for #786. Sorry for the sorry for the confusion.
