When I open HTML files in VS Code, "Dart from Flutter: 1.22.4" label is displayed in bottom bar. I went through settings of VS Code but I could not find a way to fix. Then I searched Google and found a SO question. Then I came here. I searched in issues but still I could not a find a solution.
Here is a screenshot
