[Windows] Begin decoupling text input plugin from the view #47833

loic-sharma · 2023-11-08T22:49:08Z

Currently the text input plugin is strongly tied to a single view. This change makes the text input plugin tied to the engine in preparation for multi-view world.

Part of flutter/flutter#115611

shell/platform/windows/text_input_plugin.h

@@ -85,7 +104,7 @@ class TextInputPlugin {
  // as TextEditingDeltas or as one TextEditingValue.
  // For more information on the delta model, see:
  // https://master-api.flutter.dev/flutter/services/TextInputConfiguration/enableDeltaModel.html
-  bool enable_delta_model;
+  bool enable_delta_model = false;


The lack of a deterministic default value caused optimized unit tests to send delta model messages unexpectedly.

Strange - this should be default zero-initialized. Do we know in which specific situations there were problems?

fwiw even if only for readability as a declaration of intent, we should make this change.

Alrighty then

Can we land this? Looks good to go.

shell/platform/windows/text_input_plugin.h

+  //
+  // Triggered when the user commits the current composing text while using a
+  // multi-step input method such as in CJK text input. Composing continues with
+  // the next keypress.


uber-nit: it's not necessarily the user who explicitly performs a commit -- in Korean, for example, just typing the next character is enough to trigger a commit of the composing region. Maybe "Called when the user triggers a commit of the [...]" to be very slightly more accurate.

Thanks for the additional info, I'm not very familiar with this area. Updated! :)

+  // Called on an IME compose end event.
+  //
+  // Triggered when the user commits the composing text while using a multi-step
+  // input method such as in CJK text input.


In this case called when composing ends, which is often preceded by a commit, but if they press ESC, for example, won't be.

Updated this!

style (here and the next one): Use UpperCamelCase for methods. For simple accessors and mutators, you can use the same naming as variables (e.g., engine and set_engine).

The ones above all look good!

Fixed this and the other areas where I stole this name from :)

Looks good! Just a few small nits.

cbracken

lgtm! Looks great!

Is this safe to land?

loic-sharma · 2023-11-30T21:49:44Z

Yes, landed! :)
