GridView Builder

GridView Builder is a widget that allows you to create dynamic grid views with dynamic data. It minimizes the code for creating a grid view widget by providing a simple interface to add data to the grid.

Installation

Add the following dependency to your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter
  gridview_builder: ^1.0.0

Then run flutter packages get.

Usage

To use the GridView Builder widget, simply import the package and create a GridView Builder widget. You can add the data that you want to display in the grid view using the add method. The add method takes a List of Widgets to be displayed in each grid view cell.

Here's an example of using the GridView Builder widget:

import 'package:flutter/material.dart';
import 'package:gridview_builder/gridview_builder.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'GridView Builder Demo',
      home: Scaffold(
        appBar: AppBar(
          title: Text('GridView Builder Demo'),
        ),
        body: Center(
          child: GridViewBuilder(
            crossAxisCount: 4,
            mainAxisSpacing: 10.0,
            crossAxisSpacing: 10.0,
            childAspectRatio: 1.0,
            padding: EdgeInsets.all(2.0),
            itemCount: 16,
            itemBuilder: (BuildContext context, int index) {
              return Container(
                color: Colors.green,
                child: Center(
                  child: Text('$index'),
                ),
              );
            },
          ),
        ),
      ),
    );
  }
}

The above code will create a grid view with 16 cells, each of which displays the index of the cell. You can customize the appearance of the grid view by setting the values of the various properties of the GridView Builder widget.
