In android, we can set max lines for text view like this:

```
<TextView
    android:id="@+id/text"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"  
    android:maxLines="5" />

```

However in flutter, we can do that by adding max height constrains, but we need to know what exactly the height is.

Is there any way we can easily specify the max lines for Text/RichText?
