iPhone 13

After much speculation, Apple will host an event on September 14 and it will most likely be the debut of the iPhone 13.

Apple has confirmed this through an event poster it sent to the press, which very clearly marks the September 14 launch event. Apple’s senior vice president of marketing tweeted this short clip, not hinting at any device though.

Design

They are expected to change little from the iPhone 12, but it appears that the company will change the design of the rear camera. It will apparently have a diagonal lens arrangement.

Color

Apple may introduce some new shades with the iPhone 13 series, with two versions rumored to be pink and orange. Along with them, we expect to see shades similar to those of the last generation, such as purple, black and white.

Display

Screen sizes and resolutions are expected to remain the same across the entire iPhone 13 product line, but both the iPhone 13 Pro and iPhone 13 Pro Max are rumored to debut with 120Hz refresh rates. That means the image on these screens will be smoother than on previous iPhones.

Camera

Apple is expected to be tweaking the camera on the iPhone 13 series, and the two Pro phones can get an improved ultra-wide shooter. The iPhone 13 Pro may also have an improved telephoto camera, plus some leaks suggest LiDAR could be present in all four models, so it will have improved depth perception, although the most recent leaks don’t mention this.

Others

The A15 chipset will likely power each of these phones, although current reports suggest this won’t bring a huge power boost. It is also widely rumored that Apple may release a 1TB iPhone for the first time in 2021, thus allowing for the largest iPhone sizes ever. You can also expect a bigger battery inside the 2021 phones. They are expected to be noticeably larger, expecting an iPhone 13 more durable than your previous iPhones.

Flutter – Clipboard

This week also let’s learn flutter new things. I will show you how to copy and paste a text with flutter. Let’s start coding.

First thing we need to do is add this clipboard package in pubspec.yaml file.

flutter pub add clipboard

Copy to clipboard

FlutterClipboard.copy(field.text).then(( value ) => print('copied'));

Paste from clipboard

FlutterClipboard.paste().then((value) {
    // Do what ever you want with the value.
    setState(() {
      field.text = value;
      pasteValue = value;
    });
  });

For text editing field :

TextEditingController field = TextEditingController();
TextFormField(
                controller: field,
                decoration: const InputDecoration(
                    hintText: 'Enter text'
                ),
              ),
