flutter motion transitions

a fultter app to demonstrate material motion system.

material motion system

the four main material transition patterns are as follows:

container transform:

transitions between ui elements that include a container; creates a visible connection between two distinct ui elements by seamlessly transforming one element into another.

shared axis:

transitions between ui elements that have a spatial or navigational relationship; uses a shared transformation on the x, y, or z axis to reinforce the relationship between elements.

fade through:

transitions between ui elements that do not have a strong relationship to each other; uses a sequential fade out and fade in, with a scale of the incoming element.

fade:

used for ui elements that enter or exit within the bounds of the screen.
