在迁移期间使列默认值不在laravel 5.5中工作

I am trying to give 'is_img' column to default value '0' during migration. When I am trying like - $table->integer('is_img')->defalut(0)->change(); It's removing existing column during migration. When trying without change() method, then it's giving null value during migration. What should I do to keep the default value for the column during migration? Here is Schema bellow -

public function up()
{
    Schema::create('admins', function (Blueprint $table) {
        $table->increments('id');
        $table->string('email');
        $table->string('user_name');
        $table->string('password');
        $table->string('login_type');
        $table->integer('is_img')->defalut(0)->change();
        $table->timestamps();
    });
}

You have a typo in this line:

$table->integer('is_img')->defalut(0)->change();

Should be default(0) not defalut(0).

It was typo mistake to 'defalut', should be 'default', $table->integer('is_img')->default(0); is working fine. Thanks @Esteban Garcia and @Hiren Gohel for saving my time.
