Flutter: How to set the minimum height to Widget?

This is a very common thing that comes in day-to-day development, but I found in Flutter there is no such documents available that explain this concept in short. So, now I will try to explain in short as possible.

First, required BoxConstraints which provides the boundaries to the Widget, it has params like:

this.minWidth = 0.0,
this.maxWidth = double.infinity,
this.minHeight = 0.0,
this.maxHeight = double.infinity,

Above are the default params which have for every widget, here we need to modify two params which will do our job

1. minWidth — The minimum width that satisfies the constraints
2. maxHeight — The minimum height that satisfies the constraints.

Container(
          color: Colors.blueAccent,
          constraints: BoxConstraints(
              minHeight: 100, minWidth: double.infinity, maxHeight: 400),
          child: ListView(
            shrinkWrap: true,
            children: <Widget>[
              ...List.generate(
                10,  // Replace this with 1, 2 to see min height works. 
                (index) => Text(
                  'Sample Test: ${index}',
                  style: TextStyle(fontSize: 60, color: Colors.black),
                ),
              ),
            ],
          ),
        ),

Output for Min Height for Single Item:

Output for Min Height for 10 Items:

Note: This will show widgets as per mentioned max-height. The above image clearly tells you that it shows only half Texts not all of them, as max height is mentioned.
