When i create LinearPercentIndicator like this:

Expanded(
         flex: 0,
              child: new LinearPercentIndicator(
                lineHeight: 6.0,
                width: 140.0,
                percent: 0.5,
                animation: true,
                backgroundColor: Colors.lightGreenAccent,
                progressColor: Colors.deepPurple,
              ),
        )

Flutter test excute correctly. But when i pass data from StateFull or Stateless parent widget like 

Expanded(
          flex: 0,
              child: new LinearPercentIndicator(
                lineHeight: 6.0,
                width: 140.0,
                percent: percent,
                animation: true,
                backgroundColor: Colors.lightGreenAccent,
                progressColor: Colors.deepPurple,
              ),
        ),

Flutter test give me the following error log

The following NoSuchMethodError was thrown building ArticleDescription(dirty, dependencies:

00:08 +5 -1: /home/eli/Documents/user/Mobiles/amala/amala_statistics/lib/test/w_linear_progress_test.dart: Linear Progress Widget Test [E]   
  Test failed. See exception logs above.
  The test description was: Linear Progress Widget Test

I tried to figure out the causes of failure finaly i found this happened only when LinearPercentIndicator values are passed from parrentWidget to LinearPercentIndicator as child
