Flet is a fast-evolving framework with a new functionality and bug fixes being committed every other day.

The development model with one pull request per release didn't work well for the project as users waited for weeks to get hands on a new release and, honestly, from development perspective producing large "heroic" releases takes a lot of energy 🫠.

From now on we'll be breaking releases into multiple pull requests with one feature/bugfix per PR.

Every PR merged into main branch will be publishing pre-release (developmental release) package to pypi.org having version format of X.Y.Z.devN.

We just released Flet 0.1.65 which is adding a bunch of mobile-optimized controls, fixing some bugs and introducing a new layout control - ResponsiveRow.

ResponsiveRow control​

ResponsiveRow borrows the idea of grid layout from Bootstrap web framework.

ResponsiveRow allows aligning child controls to virtual columns. By default, a virtual grid has 12 columns, but that can be customized with ResponsiveRow.columns property.

Similar to expand property every control now has col property which allows specifying how many columns a control should span. For example, to make a layout consisting of two columns spanning 6 virtual columns each:

import flet as ft

ft.ResponsiveRow([
    ft.Column(col=6, controls=ft.Text("Column 1")),
    ft.Column(col=6, controls=ft.Text("Column 2"))
])

We are thrilled to introduce Matplotlib and Plotly charting controls in Flet 0.1.63!

Matplotlib and Plotly are the most recognized Python charting libraries with a ton of features. They are greatly compatible with other scientific Python libraries such as Numpy or Pandas.

No doubt, it would be nearly impossible to replicate their functionality as pure Flutter widgets. Fortunately, both Matplotlib and Plotly can export charts into various formats, such as SVG. On the other hand Flet can display SVG images and that gives a perfect combination - Flet charting controls for Matplotlib and Plotly!

The resulting solution works so great that it's possible to display almost any example from Matplotlib and Plotly galleries - your imagination is the only limit!

Plot a simple bar chart:

a nice scatter with legend:

or some multi-chart contour plot:

We've just released Flet 0.1.62 with support of gestures processing!

There is a new control - GestureDetector which allows handling all sorts of gestures: single and double taps with a left (primary) and right (secondary) mouse (pointer) buttons, vertical, horizontal and bi-directional drags, zoom (pinch-in and pinch-out) gestures as well as hover events. Now, by wrapping it into GestureDetector, you can make any Flet control "clickable" and "draggable"!

Here is a simple example of an app which allows you to drag containers inside a Stack:

User authentication in Flet is here! 🎉

Now you can implement user authentication ("Login with X" buttons) in your Flet app using 3rd-party identity providers such as GitHub, Google, Azure, Auth0, LinkedIn and others:

Traditionally, this release is not just about authentication, but it adds a ton of accompanying functionality and small improvements:
