can ConstraintLayout help to flow the right side item to next line?

AFAIK, flowing views from one line to the next is not something that ConstraintLayout can do. It is, however, something that FlexboxLayout can do very easily.

Here is an initial introduction to the technology. There are also a few good apps on the Play store to play around with the layout.

FlexboxLayout can be interpreted as an advanced LinearLayout because both layouts align their child views sequentially. The significant difference between LinearLayout and FlexboxLayout is that FlexboxLayout has a feature for wrapping.

I know I am pretty late to the party but to anyone who's still subscribed to this question, as of today ConstraintLayout 2.0 (just launched in beta1) supports a new ConstraintHelper called Flow using which your specific requirement can be fulfilled in ConstraintLayout.

Flow

The following are the release notes for beta1

you can use com.google.android.material.chip.ChipGroup like this

<com.google.android.material.chip.ChipGroup
      android:layout_width="0dp"
      android:layout_height="wrap_content"
      android:layout_marginTop="8dp"
      android:layout_marginStart="8dp"
      android:layout_marginEnd="8dp"
      app:layout_constraintEnd_toEndOf="parent"
      app:layout_constraintStart_toStartOf="parent"
      app:layout_constraintTop_toBottomOf="@+id/title">
      <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="aaaaaaa"
        android:textSize="10sp"/>

      <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="bbbbbb"/>

      <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="cccccccc"/>

      <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="fffffffff"/>

      <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="hhhhhhh"/>
      <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="trtr"/>
    </com.google.android.material.chip.ChipGroup>

after searching around and conclusion is ConstraintLayout is to flatten the view hierarchy of the layouts to avoid nesting, to optimize the view hierarchy. So as @Cheticamp pointed out "ConstraintLayout does not have that particular capability". So closing this question.
