Tips
1. Apply HitTestBehavior.opaque on GestureDetector
If your GestureDetector isn’t capturing gestures on a transparent widget, set its behavior to HitTestBehavior.opaque. This allows it to capture events throughout its area.
GestureDetector(
behavior: HitTestBehavior.opaque,
onTap: () => print('Tap!'),
child: Container(
height: 250,
width: 250,
child: Center(child: Text('Gesture Test')),
),
);
2. Check if running in release mode
To verify if your app is running in release mode, use the kReleaseMode constant. If it’s configured with the appropriate flag, it’ll return true.
import 'package:flutter/foundation.dart';
print('Is Release Mode: $kReleaseMode');
3. Set background image to your Container
Instead of using a Stack for background images, utilize the BoxDecoration for a cleaner implementation.
Container(
width: double.maxFinite,
height: double.maxFinite,
decoration: BoxDecoration(
image: DecorationImage(
image: NetworkImage('https://bit.ly/2oqNqj9'),
),
),
child: Center(
child: Text(
'Flutter.dev',
style: TextStyle(color: Colors.red),
),
),
);
4. Use assert() for validation
The assert() function allows you to throw a message when the assertion fails, providing better debugging insights.
assert(title != null, 'Title string cannot be null.');
5. Implementing Plurals in strings
With the Intl package, you can manage pluralization effortlessly.
import 'package:intl/intl.dart';
notificationCount(int howMany) => Intl.plural(
howMany,
zero: 'You don\'t have any notifications.',
one: 'You have $howMany notification.',
other: 'You have $howMany notifications.',
name: 'notification',
args: [howMany],
examples: const {'howMany': 42},
desc: 'How many notifications are there.',
);
print(notificationCount(0));
print(notificationCount(1));
print(notificationCount(2));
6. Ternary operator for concise code
Adopt the ternary operator for more compact if-else statements in your Dart code.
bool isAndroid = true;
getDeviceType() => isAndroid ? 'Android' : 'Other';
print('Device Type: ' + getDeviceType());
