Proposal to add default `duration` for `AnimatedSwitcher`

[nilsreichardt]

I'm using the AnimatedSwitcher widget in a lot of situations, and I'm loving this widget ❤️ But I'm forced to pass always a duration, because duration is required.

Is there a specific reason, why there is no default value for duration, like 250ms? Reading through Material Design Guidelines, a default value of 250ms would be a good choice. Of course, the developer can still provide his own duration, because it would only be a default value.

I would love to see an answer to this 🙂 If we can remove the required tag from duration, I can open a PR for this.

Hi @nilsreichardt, This issue looks more of a proposal to me and if valid a default duration of 250ms should be set for all ImplicitlyAnimatedWidgets and not just the AnimatedSwitcher

AnimatedSwitcher is a very basic widget from the widget library, which shouldn't have build-in assumptions (from material or elsewhere). You could just write a wrapper widget around AnimatedSwitcher that uses a default duration.
