How I Built a Flutter Custom Multi-Select Dialog Package

#flutter #dart #android #package

Building custom dialogs in Flutter can be tricky when you want more than the basics.

I recently built a custom multi-select dialog package to make developer life easier — here’s how.

Why a Custom Multi-Select Dialog?

Flutter’s built-in dialogs are great for simple confirmation boxes, but when it comes to multi-selection with titles, subtitles, and customization, you often end up reinventing the wheel.

So I decided to create my own reusable package.

Features I Needed

✅ Multiple item selection
✅ Support for title & subtitle
✅ Reusable across projects
✅ Clean MVVM-friendly structure

Core Implementation

showDialog(
  context: context,
  builder: (context) {
    return MultiSelectDialog(
      title: "Choose Items",
      items: ["Option A", "Option B", "Option C"],
      onConfirm: (selected) {
        print("Selected: $selected");
      },
    );
  },
);
