This app allows users to easily create custom container designs in Flutter by providing options to adjust gradients, shadows, and borders. Users can choose from various gradient types, set shadow effects, and customize border styles (including thickness and radius). They can preview these changes in real-time and generate the corresponding Flutter code. With a "copy to clipboard" button, users can quickly copy the generated code and integrate it into their projects, streamlining the process of adding personalized containers to their Flutter apps.
