Laravel Migration make existing column nullable

Create a new migration

php artisan make:migration change_description_products_table

In the new file add this to the function up():

Schema::table('your_table_name', function (Blueprint $table) {
    $table->text('your_field_name')->nullable()->change();
});

Make sure you install doctrine/dbal because it’s required for this.

composer require doctrine/dbal

Now you can run your migrations.

php artisan migrate
