🚀 Performance Boosts & Stability Improvements
One of the highlights of Flutter 3.27 is the continued focus on performance and stability. This update fine-tunes rendering, memory management, and animation performance to ensure smoother experiences across all platforms. If you've noticed lag or jank in animations before, this update might just be the fix you need.Wait a minutes, Why I am telling you? Let's update and practice it. Here is the keys you need to remember.
Flutter 3.27 brought several noteworthy updates, and here are some key changes:
1. Row and Column Spacing
No more manual SizedBox or Padding for spacing! With Flutter 3.27, both Row and Column now support the spacing parameter. This adds uniform spacing between child widgets automatically.
// Before Flutter 3.27
Row(
children: [
Icon(Icons.home),
SizedBox(width: 10), // Manual spacing
Icon(Icons.settings),
SizedBox(width: 10), // Manual spacing
Icon(Icons.notifications),
],
);
// With Flutter 3.27
Row(
spacing: 10, // Automatic spacing
children: [
Icon(Icons.home),
Icon(Icons.settings),
Icon(Icons.notifications),
],
);
// Similarly for Column
Column(
spacing: 20,
children: [
Text('Hello'),
Text('World'),
],
);
2. Text Selection Improvements
Selecting text in Flutter-based desktop apps is more intuitive now! The new release brings Shift + Click support to move the selection extent, plus better APIs for clearing text selection
SelectableRegionState? selectableRegionState =
_selectableRegionKey.currentState;
selectableRegionState?.clearSelection();
To use this, you need to provide a GlobalKey to the SelectionArea:
GlobalKey _selectableRegionKey = GlobalKey();
SelectionArea(
key: _selectableRegionKey,
child: // Your selectable text widget
);
3. CupertinoSlidingSegmentedControl Improvements
Visual and functional improvements include proportional layouts based on segment content, adjustments to thumb radius, separator height, and padding.
CupertinoSlidingSegmentedControl<int>(
groupValue: selectedSegment,
children: {
0: Text('Home'),
1: Text('Settings'),
},
onValueChanged: (int? newValue) {
setState(() {
selectedSegment = newValue;
});
},
);
4. CarouselView Enhancements
CarouselView has more features in the new release.
CarouselView.weighted(
itemWeights: [0.5, 0.3, 0.2],
items: [
Image.network('https://via.placeholder.com/150'),
Image.network('https://via.placeholder.com/100'),
Image.network('https://via.placeholder.com/50'),
],
);
