The command "flutter test ${test-example_test.dart}" is a command used in the Flutter framework to run unit tests.

Let's break down the command into its components:

1. "flutter": This is the keyword that specifies the use of the Flutter framework.

2. "test": This is a subcommand provided by Flutter that allows you to run your test files.

3. "${test-example_test.dart}": This is the argument passed to the test subcommand. This argument specifies the test file(s) that you want to run. In this case, it looks like the argument is referring to a test file named "example_test.dart". The use of "${}" is a syntax for referencing variables or expressions within a command line context, but in this case, it appears to be used incorrectly since it should be referencing an actual variable.

To use the correct syntax, it should be either:

• If you want to run a single test file:

  flutter test test-example_test.dart

• If you want to run all test files in the test directory:

  flutter test test/

It's worth noting that the command might differ based on your specific project structure.
