Set size while keeping window centered

[chimon2000]

Currently, the window grows downward and to the right, causing it to lose its positioning.

It would be nice to be able to set the size of the application window while keeping the window centered in the same call.

We have a setBounds method that can set both position and size, You can use the screen_retriever plugin to get the screen size and then calculate the correct new position

Rect bounds = Rect.fromLTWH(10, 10, 800, 600);
windowManager.setBounds(bounds);

You can refer to the setAlignment method.

	/// Move the window to a position aligned with the screen.
	Future<void> setAlignment(Alignment alignment) async {
	Size windowSize = await getSize();
	Map<String, dynamic> primaryDisplay = await _getPrimaryDisplay();
	num visibleWidth = primaryDisplay['size']['width'];
	num visibleHeight = primaryDisplay['size']['height'];
	num visibleStartX = 0;
	num visibleStartY = 0;
	if (primaryDisplay['visibleSize'] != null) {
	visibleWidth = primaryDisplay['visibleSize']['width'];
	visibleHeight = primaryDisplay['visibleSize']['height'];
	}
	if (primaryDisplay['visiblePosition'] != null) {
	visibleStartX = primaryDisplay['visiblePosition']['x'];
	visibleStartY = primaryDisplay['visiblePosition']['y'];
	}
	Offset position = Offset(0, 0);
	if (alignment == Alignment.topLeft) {
	position = Offset(0, 0);
	} else if (alignment == Alignment.topCenter) {
	position = Offset(
	visibleStartX + (visibleWidth / 2) - (windowSize.width / 2),
	visibleStartY + 0,
	);
	} else if (alignment == Alignment.topRight) {
	position = Offset(
	visibleStartX + visibleWidth - windowSize.width,
	visibleStartY + 0,
	);
	} else if (alignment == Alignment.centerLeft) {
	position = Offset(
	visibleStartX + 0,
	visibleStartY + ((visibleHeight / 2) - (windowSize.height / 2)),

	}
	await this.setPosition(position);

@lijy91 setBounds currently ignores the animate property.

window_manager/lib/src/window_manager.dart

Lines 270 to 274 in c243222

	/// Resizes and moves the window to the supplied bounds.
	Future<void> setBounds(Rect bounds, {animate = false}) async {
	await setPosition(bounds.topLeft);
	await setSize(bounds.size);

@lijy91 setBounds currently ignores the animate property.

i will fix it
