A migration to save a date_picker field would be:

Schema::table('posts', function (Blueprint $table) {
    ...
    $table->date('event_date')->nullable();
    ...
});
// OR
Schema::table('posts', function (Blueprint $table) {
    ...
    $table->dateTime('event_date')->nullable();
    ...
});

When used in a block, no migration is needed.
